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.
Claims15
A method comprising:
- selecting, by a processor, a precoding matrix to use for channel encoding 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 to encode a source for transmission over a multiple input multiple output (MIMO) channel;
- and
- a precoding component to precode the source with a precoding matrix selected to reduce distortion between the source and a reconstructed source induced by transmission of the source over the MIMO channel.
