OFDM系统的仿真代码MATLAB环境下

This matlab code simulates a single data packet communication through a complete siso-ofdm system with transmitter, channel and reciever.

The transmitter part includes convolution coding, interleaving, mapping, adding pilot symbols, ifft transforming, adding prefix and power amplifying.

The channel is the combination of multi-path channel and AWGN channel. 

The reciever part includes removing prefix, fft transforming, channel estimation, demapping, deinterleaving, viterbi decoding and BER evaluation.

This system has some certain flexability. Because the coding rate and the mapping scheme is optional. And many other factors are adjustable according to the practical situation.

What's more importand, this system is ready for function expansion and can be used as a universal ofdm platform to evaluate different algorithms.
