摘要： The equipment and techniques disclosed herein introduce a deferred acknowledgement (DACK), in the context of a protocol for a wireless station to request and obtain access to a wireless network resource for communication of one or more data packets. Essentially, a network node, such as a wireless base station, sends the DACK instruction in response to the access request telling the requesting station that the node has heard the request but that the requesting station should defer its transmission. The requesting station need not back off and re-initiate its access request. Instead, the requesting station waits for a later acknowledgement (ACK) granting access to a resource as requested. Although the DACK provides additional signaling, this technique can still utilize a fast ACK type message, that is to say a relatively short signaling packet.

摘要： An enhanced spread-spectrum uplink technique provides more efficient packet transfer in a wireless network. A mobile station requests to utilize an uplink channel, typically, a physical dedicated channel. If the network will grant access, a base station sends back a channel-request-granted message, which specifies a transmission start time and length. The base station starts related downlink transmissions at the start time, and at a time thereafter, the mobile station starts sending packet data over the uplink physical dedicated channel. After a transmission of no more that the specified length, the mobile station ceases its uplink transmission on the dedicated channel, and the base station and/or the mobile station can immediately release one or more channel resources. The grant message and/or the subsequent signaling communications from the base station may also specify a modulation scheme and a channelization code for the uplink channel.

摘要： A multi-clock matched filter for receiving signals with multipath. The signals may be modulated with a spread-spectrum spreading sequence, or other analog or digital signal. A number of signal registers store digital samples of the received signal. The gating of digital samples into each of the signal registers is controlled by a separate clock timing. The timing sequence may be derived from a common clock. A multiplexer sequentially selects each of the signal registers, and passes the respective content of each signal register to a matched filter. A number of delay-locked-loop circuits track each of the multipath signals, and generate the timing sequence for gating signal registers.

摘要： Data is transferred between a plurality of processors. A plurality of light beams is produced. The light beams have at a particular time a single wave length. The single wavelength is selected from a plurality of wavelengths. Each light beam is uniquely associated with a processor. Each processor selectively modulates data onto its light beam. At a particular time, the selected wavelength of the single wavelength and the processors modulating data onto their light beam is controlled. The plurality of light beams is received at an input ring array. The light beams from the input ring array are transferred to an output ring array. Each light beam is rotated. Each selected wavelength is uniquely associated with a particular rotation. A light beam is output to each processor from the output ring array.

摘要： A spread-spectrum-matched-filter apparatus including a code generator, an in-phase-symbol-matched filter, a quadrature-phase-symbol-matched filter, an in-phase-frame-matched filter, a quadrature-phase-frame-matched filter, and a controller. The code generator generates replicas of a chip-sequence signal, which are used to set the symbol-impulse responses of the in-phase-symbol-matched filter and the quadrature-phase-symbol-matched filter. The in-phase-frame-matched filter and the quadrature-phase-frame-matched filter detect a despread-header-symbol-sequence signal and generate a maximum output signal which may be used as a data-start signal or for synchronizing the timing of the controller as to when to trigger sampling of the A/D converter, the output of the symbol-matched filters, detection of the data-symbol-sequence signal and other time-dependent processes.

摘要： A spread-spectrum-phase-locked-loop apparatus and method for coherent detection without a pilot channel. The system comprises symbol-matched means, a voltage-controlled oscillator (VCO), a first product device, a second product device, a third product device, a fourth product device, a first combiner, a second combiner, and a fifth product device. The method comprises the steps of despreading, from a received spread-spectrum signal, an in-phase component and a quadrature-phase component of a symbol sequence signal using the symbol-matched means. The first and second product devices multiply the despread in-phase component by the VCO-cosine and the VCO-sine signals, respectively, to generate a first and a second product signal. The third and fourth product devices multiply the despread quadrature-phase component by the VCO-sine and the VCO-cosine signals, respectively, to generate a third and a fourth product signal. The first combiner combines the first and third product signals to generate a first combined signal. The second combiner combines the second and fourth product signals to generate a second combined signal. The fifth product device multiplies the first and second combined signals to generate an error signal, responsive to which the VCO adjusts the sine and cosine signal levels.

摘要： The present invention has application to countering IEDs which are triggered remotely through a RF signal directed at, or the same operating environment as, receiver components embedded in, or part of, commercially manufactured cell phones or remote control devices. The invention exploits those situations where the underlying device (i.e., a commercial cell phone) is designed to operate in an environment where noise is characterized by an additive Gaussian noise model. The invention exploits the optimization of the matched filter for Gaussian noise by introducing a specific non-Gaussian noise. Further, the invention is directed to a family of jamming waveforms which exhibit increased effectiveness against a variety of digital and analog communications systems.

摘要： An improvement to a code-division-multiple-access (CDMA) system employing spread-spectrum modulation, with the CDMA system having a base station (BS) and a plurality of remote stations. The base station has a BS-spread-spectrum transmitter and a BS-spread-spectrum receiver. A remote station has an RS-spread-spectrum transmitter and an RS-spread-spectrum receiver. The BS transmitter transmits a broadcast common-synchronization channel, which includes a frame-timing signal. The broadcast common-synchronization channel has a common chip-sequence signal, which is common to the plurality of remote stations. In response to the RS-spread-spectrum receiver receiving the broadcast common-synchronization channel, and determining frame timing from the frame-timing signal, an RS-spread-spectrum transmitter transmits an access-burst signal. The access-burst signal includes a collision-detection portion. In response to the BS-spread-spectrum receiver receiving the access-burst signal, the BS-spread-spectrum transmitter transmits an collision-detection signal with the collision detection portion. In response to the BS-spread-spectrum receiver not receiving the access-burst signal due to a collision with a collision access-burst signal, the BS-spread-spectrum transmitter transmits an collision-detection signal without the correct collision detection portion.

摘要： A method is disclosed by which the data rate of the transmission on a communications link is adjusted according to the underlying channel conditions based on a fast Layer-1 feedback Channel Quality Indicator (CQI) control signal received on the return channel. The method enables the system to transmit a data packet of information at different symbol rates during the transmission of a data packet. Each data packet is transmitted over a number of time slots, with the transmission rate or the modulation scheme used in each time slot is changed dynamically during the transmission of the data packet according to channel quality indicators received from the reverse link.
