OFDM Trasnmitter and Receiver (Matlab Code)

OFDM code with 16-QAM modulation. Can be easily Understood and modified.

Description

This code basically computes the BER of an OFDM system. The ifft size is 64 .16-QAM is the modulation Technique and convolution encoding rate 1/2 is used as the coding scheme.

• MATLAB release: MATLAB 7.0.4 (R14SP2)

Well done! A few parts I feel could be done better (specifically the choice of using trellis and pilot insertion) but all in all quite straight forward and easily understood. Thanks!

can any one help me in this topic"Interference Suppression for OFDM Systems With
Insufficient Guard Interval Using Null Subcarriers"

I found a problem with this code.
When no noise is added and when the rxed_data is collected for every frame, then there is an error when compared to t_data

[Kaushik]

sorry! I was wrong! the code is perfectly working!!

how can it working.that just demo.they cut some where in the code

[quy nguyenminh]

hi every body.i had 1 proplem about the ofdm simulate.this is the last year i study at shool.so i have 1 project that about OFDM.but i did'nt know how to simulate that.some one cuold show me.thanks alot.and what'll i do first?
