    摘要: A communication device configured for wireless communications includes a detector configured to perform demodulation on a plurality of received modulation symbols to identify a plurality of source transmitters for the plurality of received modulation symbols, and a selector configured to compare spectrum envelopes of the plurality of received modulation symbols with a spectrum envelope of a target received modulation symbol to select one or more of the plurality of source transmitters, the detector further configured to perform demodulation on the target received modulation symbol based on the selected one or more of the plurality of source transmitters to identify a source transmitter for the target received modulation symbol.

    摘要: A communication device is provided that includes a baseband circuit and a transmitter configured to transmit a first signal and a projected signal. The baseband circuit is configured to determine the projected signal based on an estimated signal state information such that an energy of a shaped projected signal is smaller than an energy of a shaped signal. The estimated signal state information is an estimate of a signal state information based on the first signal and a received signal that is received by a receiver of the second communication device. The shaped projected signal is the projected signal received by the receiver of the second communication device and filtered by a filter of the second communication device. The shaped signal is the received signal filtered by the filter of the second communication device.
