Dear All, I'm doing my final year project in Digital Signal Processing using Matlab. I would like to ask for few suggestions or inputs from you. A very brief description of my FYP project: I have to split an input signal (formed from N samples) in M frequency bands (for example 4 bands). After this he I will have to do a polyphase decomposition of the signals from the M (or 4) frequency bands. After accomplishing the above things, next is a data processing. After all these I'll need a synthesis filter bank, which relying on the signals from the M (or 4) bands, will have to reconstruct the original signal. My concern would be, that how these analysis / synthesis filters (reconstruction filter banks) should be be generated with Matlab code? How should I implement the analysis multirate filters (splitting the signal in more frequency bands), and the synthesis multirate filters (reconstruction of the original signal from the frequency band components) in Matlab? I will not have to get involved in the data processing after the splitting in more frequency bands. Thank you in advance for any suggestions! Regards, LM |
