1. A method comprising:
selecting one or more parameters for channel encoding of an encoded source for minimizing distortion between the encoded source and a reconstructed encoded source induced by transmission of the source over a multiple input multiple output (MIMO) channel, wherein the one or more parameters selected for minimizing distortion comprises a MIMO modulation and coding scheme (MCS) and a precoding matrix, wherein the MIMO MCS and precoding matrix are selected by:
randomly generating a plurality of MIMO channel realizations with known statistics;determining instantaneous received signal-to-noise ratios for a plurality of MIMO MCS schemes and precoding matrices for the plurality of MIMO channel realizations;determining a packet error rate for the plurality of MIMO MCS schemes and precoding matrices;calculating average end-to-end distortion values for the MIMO MCS schemes and the precoding matrices based on the packet error rates;selecting a MIMO MCS scheme and precoding matrix that minimizes the end-to-end distortion based on the calculated average end-to-end distortion values; and performing channel encoding on the encoded source using the selected one or more parameters to provide channel-encoded data for transmitting the encoded source over the MIMO channel; performing source encoding on the source with a source encoder prior to the channel encoding; receiving rate distortion information from the source encoder, wherein the rate distortion information is used for selecting the one or more parameters for minimizing the distortion, wherein the receiving is performed at a channel encoder.
