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. WebAs such, the top branch of the polyphase filter in Figure 5 reduces to only one coefficient, and the total number of multiply-and-add operations is reduced from 1120 to 304 per 32-sample frame. ...
