非线性量化。读取wav文件，用2到12比特数量化。抽样频率8KHz。()

matlab function file.m-sequence, gold-sequence, crosscorrelation, autocorrelation.

实现希尔伯特-黄变换的功能，并带有一段测试数据。希尔伯特-黄变换是使用EMD分解将信号分解为本征模态函数（IMF），然后求得IMF分量的瞬时频率。其对于非稳态和非线性信号具有优良的效果。(The function plot_hht is a realization of the Hilbert-Huang transform (HHT). The HHT decomposes a signal into intrinsic mode functions (or IMFs), and obtain the instantaneous frequency data. It is designed to work well for data that are nonstationary and nonlinear.)

Simulink model of AWGN BPSK with carrier recovery.
