Abstract
Precoding parameters used for precoding of a source are selected to minimize distortion that would otherwise be induced in the source during encoding and transmission of the source over a multiple input multiple output (MIMO) channel.
Claims20
A method comprising:
- selecting, by a processor, a precoding matrix to use for precoding of a source, the precoding matrix being selected based on considerations for minimizing distortion between the source and a reconstructed source induced by transmission of the source over a multiple input multiple output (MIMO) channel;
- and
- performing precoding on the source using the selected precoding matrix to provide channel-encoded data for transmitting the source over the MIMO channel.
A system comprising:
- a transmitter having a processor to implement a channel encoder for encoding a source for transmission over a multiple input multiple output (MIMO) channel;
- and
- a precoding component that precodes the source using a precoding matrix selected to minimize distortion between the source and a reconstructed source induced by transmission of the source over the MIMO channel.
Non-transitory processor-readable storage media comprising processor-executable instructions to be executed by a processor for implementing operations comprising:
- determining a precoding matrix for transmitting a source over a multiple input multiple output (MIMO) channel, the precoding matrix being determined based on a calculated distortion between the source and a transmitted reconstructed source;
- and
- performing precoding of the source using the precoding matrix.
