Patent ID: 7295624

Claim:
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.
