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： 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 method is provided for generating a multiple band ultrawide bandwidth signal. In this method, an ultrawide bandwidth devices provides a first reference signal having a first reference frequency, and a second reference signal having a second reference frequency that is different from the first reference frequency. The device generates a first ultrawide bandwidth signal based on the first reference signal, and a second ultrawide bandwidth signal based on the second reference signal, creating two separate frequency bands. These two signals can be generated form the same base clock signal, allowing for significantly simpler implementation and modification.

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 (700, 1100) and apparatus (300) are provided in a receiver for applying a variable gain to a received signal including a transmitted codeword in accordance with an Ultra Wideband (UWB) protocol. A first signal is generated and input to a selectable gain stage including a series of selectable 0 dB and 9 dB gain elements (302-305). The first signal includes the received signal mixed with a local oscillator signal modified according to a reference codeword. A gain value is selected from the selectable gain stage to amplify the first signal and form a second signal. An output signal is generated by combining the second signal and the modified local oscillator signal.

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.
