研究生时的现代信号处理的作业，在matlab R2009b调试通过，采用波束成形技术的BER计算，主同步信号PSS在时域上的相关仿真，预报误差法参数辨识-松弛的思想，使用起来非常方便，使用大量的有限元法求解偏微分方程，包含位置式PID算法、积分分离式PID。- Modern signal processing jobs when the graduate, In matlab R2009b debugging through, By applying the beam forming technology of BER PSS primary synchronization signal in the time domain simulation related, Prediction Error Method for Parameter Identification- the idea of relaxation, Very convenient to use, Using a large number of finite element method to solve partial differential equations, It contains positional PID algorithm, integral separate PID.
