MIMO detector selection

A method, comprising:

• receiving transmissions over a channel at a receiver of a Multiple-Input Multiple-Output (MIMO) communication system, the transmissions being received from a plurality of transmitters in communication with the receiver, wherein each communication is a separate communication having a modulation and coding scheme;
• converting an estimate of the channel into an estimate, for each of a plurality of transmitters, of a bit-metric decoding rate for each of a plurality of available MIMO detectors;
• converting the estimated bit-metric decoding rate for each of the plurality of transmitters for each of the available MIMO detectors into an estimated bit error rate for each of the plurality of available MIMO detectors for each of the plurality of transmitters;
• and
• selecting one of said available MIMO detectors for use in generating log-likelihood ratios for bits transmitted from said plurality of transmitters to said receiver, wherein said one of said available MIMO detector is selected based on the estimated bit-error rates and a target block error rate.

A computer program embodied on a non-transitory computer-readable medium, said computer program comprising instructions for causing an apparatus to perform at least the following:

• receive transmissions over a channel at a receiver of a Multiple-Input Multiple-Output (MIMO) communication system, the transmissions being received from a plurality of transmitters in communication with the receiver, wherein each communication is a separate communication having a modulation and coding scheme;
• convert an estimate of the channel into an estimate, for each of a plurality of transmitters, of a bit-metric decoding rate for each of a plurality of available MIMO detectors;
• convert the estimated bit-metric decoding rate for each of the plurality of transmitters for each of the available MIMO detectors into an estimated bit error rate for each of the plurality of available MIMO detectors for each of the plurality of transmitters;
• and
• select one of said available MIMO detectors for use in generating log-likelihood ratios for bits transmitted from said plurality of transmitters to said receiver, wherein said one of said available MIMO detector is selected based on the estimated bit-error rates and a target block error rate.
