说明：   FIR model to use for the multipath delay. e.g. Multi=[1 0 0 0 0.5], has the direct signal at time 0, and a single reflection of 50 strength of the direct signal at a delay of 4 samples. MISC: 1. Over-Sampling: This sets the amount of oversampling of the time waveform, so that small time errors can be modified. Oversampling effects the multipath time, as the multipath is applied to the
