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

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 and wherein each symbol in the plurality of symbols corresponds to a number of bits, 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 each packet in a number I+1 of packets transmitted by the transmitter, wherein each packet of the number I+1 of packets as transmitted by the transmitter comprise at least a portion of a same set of symbols and are re-transmitted by the transmitter in response to a request from the receiver;
• suppression circuitry, coupled to the collection circuitry, for suppressing the interference effects in the number I+1 of packets;
• circuitry for accumulating a result corresponding to each packet of the number I+1 of packets, wherein the result corresponds to an output of the collection circuitry, and for the accumulating either prior to or after the operation of said suppression circuitry;
• circuitry responsive to signals from the suppression circuitry and for providing estimates of a group of bits;
• detection circuitry for detecting an error in a packet that comprises the group of bits;
• circuitry for sending the request to the transmitter to transmit a retransmission of a packet in response to the detection circuitry detecting the error;
• and
• circuitry, coupled to the plurality of receive antennas, for determining a channel estimate matrix;
• and
• wherein the circuitry for accumulating is coupled between the collection circuitry and the suppression circuitry;
• and
• wherein the suppression circuitry is responsive to the accumulated results corresponding to each packet of the number I+1 of packets.
