Code Examples for Matlab

UW-OFDM generator matrix (Matlab R2006b and later)

load G_64-16-12% G matrix of size (52x36)
load G_64-16-0;   % G matrix of size (64x48)
% d: vector of length 36/48 containing QAM data
% B: (64x52) matrix to introduce zero subcarriers

tx = ifft(B*G*d);  % transmit signal with a zero UW
% add UW samples
% ready to transmit



Code Example: G creation and receiver

Download - LMMSE data estimation and Sphere Decoding included.
For Sphere Decoding the files in 'sd.tgz' are needed. In this archive is the mex-file 'sd_worker_sts.mexa64' for 64bit Linux systems. You can compile a version for your system with the provided source code.
