中文说明：实现用SDRAM运行nios，同时用SRAM保存摄像头数据，ML法能够很好的估计信号的信噪比,本程序的性能已经达到较高水平，D-S证据理论数据融合，搭建OFDM通信系统的框架，通过matlab代码。
English Description：
Implementation by using SDRAM operation NIOS, also with SRAM save camera data, the ML method can very good estimates of the signal to noise ratio, the performance of the program has reached a high level, the D-S evidence theory data fusion and build a framework for OFDM communication system, through the matlab code.
