摘要： Embodiments of full duplex radios are disclosed herein. For example, a radio may include: a first transmitter, a second transmitter, and a receiver. The first transmitter may be configured to receive an input signal, process the input signal to generate a first transmit signal, and transmit the first transmit signal. The second transmitter may be configured to receive the input signal, process the input signal to generate a second transmit signal, and couple the second transmit signal into an input path of the receiver. Leakage at the receiver may thus be reduced. Some embodiments of a radio may also include a base band correction circuit and means for reducing transmitter noise that leaks into the receiver.

摘要： An echo-canceling unit for a simultaneous transmit and receive (STR) system includes at least three phase shifters instead of just two phase shifters in order to provide immunity to phase and/or amplitude imbalances. Each respective phase shifter is coupled to a transmit signal to generate an output signal comprising a selected phase shift with respect to the transmit signal. A weight calculation unit generates a corresponding amplitude-weight signal for the output signal of the phase shifter. A variable attenuator attenuates the output signal of each respective phase shifter based on the corresponding amplitude-weight signal to form an echo-cancelation signal component corresponding to the phase shifter. A first summer then sums the respective echo-cancelation signal components into a received signal containing an echo signal to form an echo-canceled signal. In some embodiments, an information handling system includes a receiver and a transmitter coupled to the echo-canceling unit.

摘要： Receivers with capability for iterative-diversity reception of COFDM digital television transmissions of repeated similarly coded data are described. Also described are receivers with capabilities for receiving COFDM digital television transmissions in which earlier transmissions of coded data are later followed by subsequent transmissions of the same data differently coded. The receivers use maximal-ratio code combining techniques for repeated components in the COFDM digital television transmissions. The receivers use turbo decoding techniques for concatenated coding of data in the COFDM digital television transmissions.
