(1)建立DQPSK调制和解调 SIMULINK仿真模型，评估其在AWGN信道和瑞利衰落信道下的误码率性能（画出信噪比变化时的误码率曲线）；
(2)基于（1）建立的SIMULINK仿真模型，分别在AWGN信道和瑞利衰落信道下发送一个实际音频文件，在接收端实时播放出来((1) the DQPSK modulation and demodulation SIMULINK simulation model is established to evaluate the bit error rate performance under the AWGN channel and the Rayleigh fading channel (the bit error rate curve when the signal to noise ratio changes).
(2) based on the (1) established SIMULINK simulation model, a real audio file is sent under the AWGN channel and the Rayleigh fading channel respectively, and it is played on the receiving end in real time.)

说明： 最大限度地平 FIR 逼近 （拉格朗日插值法）
拉格朗日插值是一种时域方法，导致基于多项式的筛选器的一个特殊情况。用 M 次多项式近似表示输出信号。最简单的情况 (M = 1) 对应于线性插值。让我们设计和分析将通过各种馏分拆分单元延迟的几种线性分数时滞滤波器：(Maximally-Flat FIR Approximation (Lagrange Interpolation)
Lagrange interpolation is a time-domain approach that leads to a special case of polynomial-based filters. The output signal is approximated with a polynomial of degree M. The simplest case (M=1) corresponds to linear interpolation. Let's design and analyze several linear fractional delay filters that will split the unit delay by various fractions:)
