摘要： A system and method distributes wireless signals to areas remote from a base station by incorporating a backplane fiber card connected to a backplane in a base station and a radio fiber card connected to a radio. The backplane fiber card and the radio fiber card are connected together by one or more fiber links, which carry signals between the two fiber cards. The radio can therefore be placed at any location within the length of the fiber link, remote from the backplane. The backplane fiber card can be plugged into a radio card slot in the backplane. In one embodiment, the fiber cards have connectors that connect to standard backplane and radio structures, allowing the invention to be incorporated in existing systems without any modifications to the radio or the backplane itself.

摘要： A wideband code division multiple access (CDMA) communication system overlayed on an IS-95 network generates two or more digital bit streams from a group of wideband digital data streams, each digital bit stream spread to form a CDMA component signal. Each CDMA component signal is combined with a corresponding IS-95 digital bit stream to form a composite CDMA signal, allowing a base station to share transmitter subsystems between the wideband and IS-95 systems. For up to three carrier frequencies, up to three composite CDMA signals are employed. A digital bit stream for a group of summed user conversations in the IS-95 system modulates a respective RF carrier frequency to generate a low-power RF signal. The CDMA component signals of the wideband CDMA system are generated so each has a chip rate identical to the chip rate of the digital bit streams of the IS-95 system. The baseband digital data streams for all wideband user conversations are summed digitally for each targeted RF carrier frequency to produce the composite wideband digital signal for each targeted frequency. In one application, each composite wideband digital signal, each at the IS-95 chip rate, is then used to modulate a carrier frequency which is either the same, or has approximately the same frequency and phase as the carrier frequency used in the IS-95 system. Three low-power RF signals are produced in the wideband system, each having the same spectral characteristics as the corresponding low-power RF signals generated in the IS-95 system. These low-power RF signals at the same frequency are combined into a single signal provided to the amplifier and antenna subsystem of a base station transmitter. In another application, each composite digital signal is digitally combined with a respective IS-95 digital bit stream prior to modulation by respective RF carrier. Therefore, signal combining between the IS-95 and wideband CDMA portions of a base station system is accomplished either digitally or with RF signals prior to amplification, thereby allowing the IS-95 system and wideband CDMA system portions of the base station to share RF filters, amplifiers and antennas of the base station transmitters.

摘要： A DPRAM is placed in the RF path before the digital to analog converter, to provide dynamic path gain compensation to the digital signal prior to conversion to an analog signal. The DPRAM stores corrections to the signal to compensate for amplitude losses in the signal arising from heat and non-linearities. The DPRAM has two sets of identical addresses. A logic switch, alternately directs an input signal to one of the two sets of addresses. Pre-calculated signal values which compensate for path gain are stored in one of the two sets of addresses in the DPRAM. The signal input to the DPRAM is directed to the other block. The value of the signal input to the DPRAM will determine the address to which the new value can be found. It is this new value which is actually input to the DAC and from which an analog signal is created. The updated values written to the DPRAM are the signal values with path gain compensation that is independently calculated and applied to the RF signal by a Dynamic Path Gain Compensation Controller (“DPGCC”). The DPGCC may apply any known algorithms to compute the path gain compensation and adjust the signal accordingly. In one advantageous embodiment the DPGCC accounts for thermal losses and non-linearity and takes into consideration overdrive protection constraints.

摘要： A processor monitors the real time forward link power utilization in a base station, and a controller regulates the real time forward link power utilization in the base station. The processor and controller operate in a feedback configuration to maintain call quality and prevent damage to the base station. The processor determines real time forward link power utilization on a per frame basis by taking samples at a per chip rate within each frame. The forward link power is then obtained by taking the mean of the samples.

摘要： A method and apparatus for guaranteeing packet delivery times in an asynchronous network includes generating a global timing schedule to synchronize the communication between the terminals of a network and, in response to at least one trigger, transmitting and receiving data according to the generated global timing schedule. To optimize bandwidth utilization, more than one terminal may transmit data during a specific time slot of each time frame of the global timing schedule as long as no more than one terminal attempts to transmit data to a common other terminal.

摘要： A method, apparatus and system for the synchronized combining of packet data in a network includes sorting data packets received during a predetermined time period into groups according to for which communications device of the network the received data packets are intended. The data packets in each of the groups intended for the respective communications devices are respectively time aligned and orthogonally combined. The respectively combined data packets intended for each of the specific communications devices are subsequently transmitted to the intended device using a single header and in a substantially compressed format.
