用matlab编写的除法计算器,能够实现除法运算(division calculator is written by matlab)

用2fsk和2ask调制解调来仿真对语音信号的提取等(With 2 FSK and 2 ask demodulation of speech signal to the simulation of extraction, etc)

使用二分坐标下降法实现对乘正定系数矩阵的求逆计算(DCD Matrix INV)

程序第一部分为模拟信号源，可以设置参数来仿真用来MUSIC谱估计的信号源，第二部分为MUSIC估计代码，对上一部分所设置的模拟信号源谱峰搜索，验证MUSIC算法(The first part of the procedure for the analog signal source, you can set parameters for the MUSIC spectral estimation simulation of signal source, the second part is estimated MUSIC code, part of the analog signal by setting the source of the spectral peak searching, validation MUSIC algorithm)

小区初搜为GSM系统中的一个关键过程，本程序为GSM小区初搜过程的第一部，查找频率校正突发的matlab程序，输入数据由采样数据得到，在转换成所需格式后进行处理。若其中包含fcch,则输出找到信息。若没有，则查找下一个突发。内付算法详细说明文档()

说明：  3GPP LTE中上行链路信道模型仿真程序(3GPP LTE uplink channel model in the simulation program)

5节点潮流计算，牛顿拉夫逊，如果需要多节点的话，自行改设参数(5-bus power flow calculation, Newton Raphson, if you need multi-node, then re-established parameters of their own)

利用prewitt边缘检测算子，实现图像的边缘检测，方法很简单(Edge detection operator using prewitt achieve edge detection, the method is very simple)

Block-interleaver/deinterleaver according to the IEEE 802.11-2007 Defined by two step-permutation : The first permutation ensures that adjacent coded bits are mapped onto nonadjacent sub-carriers. The second ensures that adjacent coded bits are mapped alternately onto less and more significant bits of the constellation and, thereby, long runs of low reliability (LSB) bits are avoided. Tested and works well

自己写的包络谱函数，可以实现对时间序列求出他的功率谱(Write their own spectral envelope function, can realize to the power spectrum of his time sequence)
