OFDM system

An OFDM Tx/Rx system without user defined funcitons

This is an OFDM system. I added the upsampling facility to let you be able to insert your PAPR reduction algorithm. It includes the following steps:
% data generation
% Mapping
% Serial to Parallel
% Oversampling
% IDFT using fast version IFFT
% Parallel to serial
% Cyclic Prefixing
% Adding Noise using AWGN
% Remove cyclic prefix part
% serial to parallel
% DFT using fast version FFT
% Down-Sampling
% Parallel to serial
% Baseband demodulation (Un-mapping)
% Calculating the Symbol Error Rate
