Wireless system with hybrid automatic retransmission request in interference-limited communications

摘要

A wireless receiver for receiving signals from an interference-limited transmitter in an interference-limited system comprising at least one transmit antenna, where the signals comprise a plurality of symbols. The receiver comprises a plurality of receive antennas and collection circuitry for collecting a plurality of signal samples with at least one symbol and with interference effects between different symbols. The receiver also comprises suppression circuitry, for suppressing the interference effects. The receiver also comprises circuitry for receiving signals from the suppression circuitry and for providing estimates of a group of bits. The receiver also comprises error detection circuitry for detecting an error in a packet that comprises the group of bits. Lastly, the receiver also comprises circuitry for requesting the transmitter to transmit a retransmission of a packet in response to detecting the error.

1. A wireless receiver for receiving signals from a transmitter comprising at least one transmit antenna in a wireless system, wherein the signals comprise a plurality of symbols, the receiver comprising:
a plurality of receive antennas; collection circuitry, coupled to the plurality of receive antennas, for collecting a plurality of signal samples from the plurality of receive antennas, wherein the plurality of signal samples comprise at least one symbol and interference effects and correspond to at least two packets transmitted by the transmitter, wherein each packet corresponds to a different encoding; accumulation circuitry, coupled to the collection circuitry, for accumulating the collected signal samples; and suppression circuitry, coupled to the accumulation circuitry, for suppressing the interference effects in the at least two packets.
