mismatched filter matlab
Match filter gives maximum peak signal power to noise power. Design of match filter in the case of white noise and color noise and its equations is available in many textbooks. If we get far from this design, we have not best SNR. This filter called mismatch filter. For example, in biphase pulse compression the match filter is the code which slides on signal. If we want to reduce the sidelobes, we can put the wightning filter after match filter but the this structure is not match filter.
