function [ OutPutSamples ] = MyTransmitter( input )
% MyTransmitter takes in a vector bits b of real valued bits (zeros and
% ones) of unknown length and outputs a vector of complex samples labeled
% as OutPutSamples of length N with unit average power. The data in input
% will be given in terms of real numbers.
