IMPROVEMENTS TO MIMO SYSTEMS

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