-% Downversion code (user distributable)
-%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
-% This code implements the preprocessing step of downconversion and is
-% not a part of the IEEE P1765 Baseline EVM Algorithm.
-% The downconversion is discussed in Section 5.1.1.2.
-% Here, we present a method to perform downconversion on a reference RF waveform.
