-% Downsampling code (user distributable)
-%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
-% This code is implementing the preprocessing step of downsampling and is
-% not a part of the IEEE P1765 Baseline EVM Algorithm.
-% The downsampling is discussed in Section 5.1.1.1.
-% Here, we present a method to perform downsampling on a measured RF or 
-% baseband time-domain waveform which is typically oversampled and needs to
-% be matched in length to the ideal waveform.
