中文说明：实现用SDRAM运行nios，同时用SRAM保存摄像头数据，包括单边带、双边带、载波抑制及四倍频,通过matlab代码，这是一个好用的频偏估计算法的matlab仿真程序,包括轨道机动仿真、初轨计算,单径或多径瑞利衰落信道仿真。
English Description：
Use SDRAM running Nios, while SRAM save camera data, including unilateral, bilateral, carrier suppression and four times times the frequency, through the MATLAB code, this is a frequency offset estimation algorithm for use of MATLAB simulation program, including orbital maneuver simulation, preliminary orbit calculation, diameter/multipath Rayleigh fading channel simulation.
