%
%Filters and decimates the incoming complex-valued signal with the FIR impulse 
%reponse stored in PulseShape.  The decimation rate is equal to SamplesPerChip.
%Decimation is simply performed by filtering every SamplesPerChip'th output 
%sample.  The "delay" and "tail" due to the filtering is removed This fuction 
%works on matrix of signal data, where each column in the the matrix is a  
%different signal
%
%Parameters
%   Input
%      IncomingSignal   Matrix   Matrix of incoming signal data.  The signals
%                                must be placed columnwise in the matrix.
%      PulseShape       Vector   Contains the FIR fitler's impulse response
%      SamplesPerChip   Scalar   Contains the oversampling rate or "decimation" 
%                                rate
%
%   Output
%      y                Matrix   Matrix of the filtered and decimated signal
%                                data.  Each column in the matrix corresponds
%                                to the corresponding signal in IncomingSignal
