Abstract
Various embodiments of a transmit diversity decoding techniques are provided. In one aspect, a method receives a first input that includes signals transmitted by M transmit antennas on C channels and received by N receive antennas, where M, N and C is each a positive integer greater than 1. The method also receives a second input that includes estimates of channel matrix elements. The method further generates an output that includes at least an estimate of a transmit signal transmitted by one of the M transmit antennas on one of the C channels based at least in part on the first and the second inputs.
Claims12
A method, comprising:
- receiving a first input that includes signals transmitted by M transmit antennas on C channels and received by N receive antennas, M, N and C each being a positive integer greater than 1;
- receiving a second input that includes estimates of channel matrix elements;
- and
- generating an output that includes at least an estimate of a transmit signal transmitted by one of the M transmit antennas on one of the C channels based at least in part on the first and the second inputs.
A processor, comprising:
- a multiple-input-multiple-output (MIMO) channel estimation module that generates estimates of channel matrix elements with respect to C channels, C being a positive integer greater than 1;
- and
- a MIMO receiver processing module coupled to the MIMO channel estimation module, the MIMO receiver processing module configured to:
- receive a first input that includes signals transmitted by M transmit antennas on the C channels and received by N receive antennas, M and N each being a positive integer greater than 1;
- receive, from the MIMO channel estimation module, a second input that includes the estimates of channel matrix elements with respect to C channels;
- and
- generate an output that includes at least an estimate of a transmit signal transmitted by one of the M transmit antennas on one of the C channels based at least in part on the first and the second inputs.
A non-transitory computer-readable medium having a set of computer-executable instructions stored thereon that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
- receiving a first input that includes signals transmitted by M transmit antennas on C channels and received by N receive antennas, M, N and C each being a positive integer greater than 1;
- receiving a second input that includes estimates of channel matrix elements;
- and
- generating an output that includes at least an estimate of a transmit signal transmitted by one of the M transmit antennas on one of the C channels based at least in part on the first and the second inputs.
