Polyphase filter decomposition
WebThe m bank polyphase filter 40′ for use as the digital filter circuit 14 of the circuit of FIG. 4 further includes a data register 112. The data register 112 includes m-bit locations 113 (where m is equal to the number of signal processing paths in the polyphase filter 40′). http://classweb.ece.umd.edu/enee630.F2012/slides/part-1_sec3_handoutAll.pdf

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.
