1. A method of processing a plurality of multiple-input multiple-output (MIMO) signals for transmission over a plurality of communication channels, the method comprising:
precoding the plurality of MIMO signals prior to transmission, the precoding incorporating channel state information in relation to the plurality of communication channels, the precoding further incorporating at least one of:
a priority ranking of an importance of a first channel of the plurality of communication channels relative to an importance of a second channel of the plurality of communication channels,
an error rate required by a channel of the plurality of communication channels, or
an amount of noise experienced by a channel of the plurality of communication channels.
