实现锁相环的基本功能，主要是用matlab实现相关的功能(PLL to achieve the basic functions, mainly related functions using matlab)

十字阵的波束形成图，包括相关的三维图，极坐标图等(Cross array beam forming diagram, including a three-dimensional view of the polar diagram)

说明：  此程序为语音信号的过零率检测，白噪声过零率远远高于语音信号，故可通过对过零率的检测判断出是不是语音信号。(This procedure for the zero rate of speech signal detection, white noise zero crossing rate is much higher than the speech signal, it can zero rate by detection of voice signal is not judged.)

Design of Filters using GUI (The code provides the user friendly GUI usage in filter design)

一本关于工程线性代数及其matlab编程方面的好书。(A book on linear algebra and engineering matlab programming books.)

BPSK信号的调制和解调，包含卷积编码和解码(BPSK modulation and demodulation of signals, including encoding and decoding convolutional)

rssi定位算法，极大似然估计法，最小二乘法，代码，极大似然估计法(rssi localization algorithm)

This is a model of a QPSK modulation system for transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC fi lters with excess bandwidth α = 0.18 are employed. The receiver includes an NDA timing recovery loop followed by a DD phase recovery loop. (This is a model of a QPSK modulation system f or transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC)

This program simulate the suspension system for a passenger car. It employes Sliding Mode Control, Skyhook Damper, Fuzzy Logic Control to control Semi-Active Suspension System
