OFDM simulation system use different modulation technique such as M-PSK M-QAM user can select that type . the program use image to be transmitted in QI mapped ,signal affected by AWGN and Fading on channel be for received

一个GPRS开发的例子，稍做修改，就可用在自己的项目中(The development of a GPRS example, some small modifications, you can use in their own projects)

In this paper, we present a Selected Mapping (SLM) PAPR reduction technique for MIMOOFDM system with special protection of Side Information (SI). Selected Mapping (SLM) is a powerful PAPR reduction technique since it does not cause any signal distortion and simple to implement. As a special protection for the Side Information (SI) of SLM technique, we propose a SI power allocation procedure. Simulation results show that our proposed technique gives significantly better BER performance than the ordinary SLM technique for MIMO-OFDM systems. Analysis for the optimum SI power allocation is also presented.
