此为非数据辅助的频偏估计算法的MATLAB仿真(data supporting this non- Offset Estimation Algorithm MATLAB)

说明：  4. 试说明卷积编解码的工作原理。请用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4 Explain the working principle of convolutional encoding and decoding. Please use the Simulink simulation convolutional coding and Viterbi decoding method used to decode, in which the encoding, decoding all write your own code (S-Function mode), instead of calling the Simulink existing encoding and decoding functions. In additive white Gaussian noise channel, signal to noise ratio and bit error rate to draw the curve.)

关于bch码的编码matlab程序。可以作为函数直接引用。(Bch code encoding matlab program. As a function reference.)

无线传感器定位算法，代码写在txt文件里面，需要请自行粘贴到MATLAB里(Wireless sensor location algorithm, code written in txt file inside, you need to paste it into your own in MATLAB)

自己编的，带有VAD语音检测的谱减法语音增强程序。(Own, and with VAD voice detection spectral subtraction speech enhancement procedures.)

说明：  在本系统中，信息序列在先经过FSK调制，经过截止频率为25kHz的低通滤波器后（把信号频率限制在25kHz），再进入混频器搬移到更高的频率发送出去，在接收端，用与发送端同步的跳频信号对其进行变频（跳频的解跳处理在此进行），取下边频，然后进行FSK的解调(In this system, the message sequence prior through FSK modulation, through the cut-off frequency of 25kHz after low-pass filter (to limit the frequency 25kHz), and then move into the mixer to a higher frequency to send out, at the receiving end used with frequency hopping synchronization signal transmitter carried on their conversion (FH' s solution to deal with this for jumping), take down side frequencies, then the demodulation of FSK)

低通滤波器 提供1种滤波器，oneself设计的need the guidance thanks!(low-pass filter with a filter types. oneself design need the guidance thanks!)
