摘要:
A wireless receiver (30x) for receiving signals from an interference-limited transmitter in an interference-limited system comprising at least one transmit antenna, wherein the signals comprise a plurality of symbols. The receiver comprises at least one receive antenna (RATx) and collection circuitry (38). The collection circuitry is coupled to the at least one receive antenna and is for collecting a plurality of signal samples from the at least one receive antenna. The plurality of signal samples comprise at least one symbol and interference effects between different symbols communicated from the transmitter to the receiver. The receiver also comprises suppression circuitry (44 or 60), coupled to the collection circuitry, for suppressing the interference effects. The receiver also comprises circuitry (46, 48, 50) for receiving signals from the suppression circuitry and for providing estimates of a group of bits and detection circuitry (52) for detecting an error in a packet that comprises the group of bits. Lastly, the receiver also comprises circuitry (52) for requesting the transmitter to transmit a retransmission of a packet in response to the detection circuitry detecting the error.
