Polyphase filter decomposition
WebA polyphase quadrature filter, or PQF, is a filter bank which splits an input signal into a given number N (mostly a power of 2) of equidistant sub-bands. These sub-bands are … 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.
