Matlab的OFDM在多径Rayleigh信道下的同步 1. 假设频率已同步，设计OFDM一种具体的采用循环前缀进行时间同步方法，用Simulink进行仿真，画出比特信噪比与捕获概率的关系曲线。 2. 设时间已同步，设计OFDM一种具体的采用循环前缀进行频率同步方法，用Simulink进行仿真，画出比特信噪比与频率同步误差的关系曲线.(Matlab-OFDM in multipath Rayleigh channel synchronization 1. Assume that the frequency has been synchronized, the design of a specific OFDM cyclic prefix for time synchronization method, using Simulink simulation to depict the bit signal to noise ratio and the capture probability curve. 2. Set up time is synchronized to design a specific OFDM cyclic prefix for frequency synchronization method, using Simulink simulation to depict the bit signal to noise ratio and frequency synchronization error of the curve.)
