Webchannels between the analysis and the synthesis polyphase matrices versus the number of input channels. When there is redundancy, the block MIMO channel (describing the overall physical channels between the transmitter and receiver) becomes a tall matrix. Hence an FIR inverse (synthesis matrix) is more likely to exist at the receiver side.
