摘要： A transceiver 400 is provided in an ultrawide bandwidth device, which includes an antenna 110, a transmitter circuit 145, and a receiver circuit 165. A transmitter amplifier 440 is provided between the antenna 110 and the transmitter circuit 145, and is configured to have an operational transmitter output impedance when the transceiver 400 is in a transmit mode and an isolation transmitter output impedance when the transceiver 400 is in a receive mode. A receiver amplifier 460 is provided between the antenna 110 and the receiver circuit 165, and is configured to have an operational receiver input impedance when the transceiver 400 is in a receive mode and an isolation receiver input impedance when the transceiver 400 is in a transmit mode. The isolation transmitter output impedance is greater than the operational receiver input impedance, and the isolation receiver input impedance is greater than the operational transmitter output impedance. Thus, a transmitter and receiver can be isolated without using a transmit/receive switch.

摘要： An integrated circuit device is provided. The integrated circuit includes an integrated circuit chip (110) having a chip input/output element (240); a packaging component (220) having a package input/output element (270); two or more connection elements (260) for connecting the chip input/output element with the package input/output element; and a protective layer (290) covering the integrated circuit chip, the two or more connection elements, and a portion of the packaging such that the package input/output element is uncovered. The two or more connection elements are configured to provide a set input/output impedance at the package input/output element. This is accomplished by considering the inductive and capacitive properties of each connection element, and selecting an appropriate number and orientation for the one or more connection elements.

摘要： A mono-cycle generating circuit includes a multiplexer, a pulse generating circuit, and a buffer circuit. The multiplexer receives data of a logical 1 or a logical 0, determines whether to generate a positive mono-cycle or a negative mono-cycle, based upon the data, and outputs clock signals varying in time based upon the data. The pulse generating circuit is coupled to the multiplexer, receives the clock signals and generates a first series of pulses including an up-pulse preceding a down-pulse, or a second series of pulses including a down-pulse preceding an up-pulse, in response to the clock signals received by the multiplexer. The buffer circuit is coupled to the pulse generating circuit and includes a switch circuit and a common mode buffer. The switch circuit generates the positive mono-cycle or the negative mono-cycle, based upon whether the first series of pulses is received from the pulse generating circuit or the second series of pulses is received from the pulse generating circuit. The common mode buffer circuit is coupled to the switching circuit and reduces noise generated by the switch circuit.

摘要： A method apparatus are provided for mitigating spectral lines in a wireless signal. First a code word is generated that is made up of a plurality of binary or ternary encoded pulses. Then a plurality of code-word-modulated wavelets are generated in response to the code word. These wavelets can be Gaussian monopulses, repeated cycles of a sine wave, or other shaped impulse signals. The plurality of code-word-modulated wavelets are then modulated with a bit of transmit data to form a plurality of data-modulated wavelets. This modulation serves to whiten the signals since the transmit data is effectively random. Finally, the plurality of data-modulated wavelets are transmitted to a remote device.

摘要： A method is provided for operating a wireless local device. In this method a local device receives a beacon for a current superframe in a common signal format. The beacon includes time slot assignment information. The local device then determines a device format for the transmission of data to a remote device based on format determination information. The device format can be one of a common signal format, and one or more wireless formats. The local device then determines one or more remote device time slots in the superframe assigned for transmission of the data to the remote device based on the time slot assignment information. Finally, the local device transmits the data in the one or more remote device time slots to the remote device using the device format.

A first device (121) generates a first signal (320) having a first duty cycle, comprising a first gated-on portion (323) and a first gated-off portion (363) in a time slot (260); and a second device (125) generates a second signal (330) having second duty cycle, comprising a second gated-on portion (333) and a second gated-off portion (363) in the same time slot (260). The first gated-on portion (323) is generated during a first segment of the time slot (260) and the first gated-off portion (363) is generated during a second segment of the time slot (260), while the second gated-on portion (333) is generated during the second segment and the second gated-off portion (363) is generated during the first segment. Media access control (MAC) can be used to further define positions within time slots (250) and provide error correction, power control, and the like. A preamble (860) can be transmitted at an increased power level to facilitate acquisition.

摘要： An ultra-wide band (UWB) waveform generator and encoder for use in a UWB digital communication system. The UWB waveform is made up of a sequence of shaped wavelets. The waveform generator produces multi-amplitude, multi-phase wavelets that are time-constrained, zero mean, and can be orthogonal in phase, yet still have a −10 dB power spectral bandwidth that is larger than the frequency of the peak of the power spectrum In one embodiment, the wavelets are bi-phase wavelets. The encoder multiplies each data bit by an n-bit identifying code, (e.g., a user code), resulting in a group of wavelets corresponding to each data bit. The identifying codeword is passed onto the UWB waveform generator for generation of a UWB waveform that can be transmitted via an antenna.

摘要： A system and method are provided for authenticating a new device in a wireless network using an authentication device. First, the new device estimates the distance between the new device and the authenticating device as a first distance measurement, and sends the first distance measurement to the authentication device. The authentication device then estimates the distance between the new device and the authenticating device as a second distance measurement. The authentication device then evaluates the first and second distance measurements to determine if they meet authentication criteria and sends authentication data to the new device only if the first and second distance measurements meet the authentication criteria. These criteria can be that they do not differ by more than a set error value or that they both are below a set maximum value.
