本工程实现了将三路合成的DSB信号用椭圆滤波器（低通，带通，高通）滤出； 其中的freqz函数，filter函数，fft函数都自己实现。 每种滤波器都分别用专门的函数分别写出，可以模块化。( This project will be three-way synthetic a DSB signal elliptic filter (low pass, band-pass, high pass) filter out Freqz function of which, the filter function, fft function. Each filter are, respectively, with a special function, respectively, to write, can be modular.)

CONVEX_HULL is a MATLAB library which reads a file containing the coordinates of a set of points in 2D, computes the convex hull of the points, and displays it.

function [M,m,df]=fftseq(m,ts,df)

The timing_recovery_1.mdl uses Simulinks variable step solver to create a continous time QPSK signal with both carrier and symbol rate errors. This is a relativly straight forward approach, but is computationally expensive. The sescond model, timing_recovery_2Q.mdl uses a purely discrete time approach using the same fractional sample delay approach as does the receiver. This can run much faster.
