信号与系统第二版清华大学出版社课后习题编程答案(Signals and Systems, Tsinghua University Press, second edition programming after-school exercise answer)

自适应陷波器的仿真程序源码，初级入门的的matlab仿真程序源码 可直接使用。 (Adaptive notch filter simulation program source code, the primary entry of the Matlab simulation program source can be used directly.)

说明：  利用均匀圆阵MVDR方法进行宽带波束形成(Broadband beamforming with uniform circular array MVDR method)

In this simulink model , QPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.
