摘要： A transmitter/receiver (1) up-converts, using an LO signal as a local oscillation signal, an IF signal having a predetermined frequency band, thereby generating a transmission signal RFTX. Moreover, the transmitter/receiver (1) generates a (LO+IF)2 signal and a (LO−IF)2 signal based on the IF signal and the LO signal. Using the LO signal obtained by adding-up of the (LO+IF)2 signal and the (LO−IF)2 signal, a reception signal RFRX is down-converted. Thus, a local oscillation signal generation unit of a receiving unit is not necessary.

摘要： A co-time, co-frequency full-duplex terminal includes a radio frequency transceiver, a power divider, a local transmitting antenna, a controllable adaptive module, and a signal mixer. The radio frequency transceiver transmits a radio frequency signal. The power divider divides the radio frequency signal into radio frequency signals in a first path and a second path. The local transmitting antenna transmits the radio frequency signal in the first path. The controllable adaptive module controls the radio frequency signal in the second path to have an amplitude equal to an amplitude of a self-interfere signal and have a phase opposite to a phase of the self-interference signal. The signal mixer mixes the radio frequency signal, after being controlled by the controllable adaptive module, with a base station signal and the self-interference signal.

摘要： A computing device with a configurable antenna. The antenna is configured through a switching circuit operating under software control. Operating characteristics of the antenna are configured based on connections between conducting segments established by the switching circuit, allowing the nominal frequency, bandwidth or other characteristics of the antenna to be configured. Because the switching is software controlled, the configurable antenna may be integrated with a software defined radio. The radio and antenna can be reconfigured to support communication according to different wireless technologies at different times or to interleave packets according to different wireless technologies to support concurrent sessions using different wireless technologies.

摘要： Signaling to control transmit/receive mode transitions of a serial half-duplex transceiver coupled externally to an integrated circuit is provided by the integrated circuit separately from a host processor of the integrated circuit with which the transceiver communicates. This can avoid slow transceiver turn-around times that may be associated with host processor control of the mode transitions.
