B样条小波的构造和基于小波变换模极大值的奇异点检测的Matlab实现。(Construction of B-Spline wavelet and wavelet modulus maxima for singularity detection using Matlab.)

multi user deection to cancel interference

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

使用matlab的m语言开发，功能为rake接收机的链路生成。其中包含短码生成成，业务信道长码生成，瑞利衰落信道代码， 哈达码变换，用户原始数据扩频和信道衰落 (Use Matlab m-language development, functional link generated for the rake receiver. Contains short code generated into business channel long code generation, code Rayleigh fading channels, Hadamard transform raw data of users spread spectrum and channel fading)

Buck DC DC Converter

里面包含了怎么找出一个函数的极点，并用spline函数画出sinc函数的包络线，稍加修改可画出其他的函数的包络线(To draw envelope of sinc function. You can modify it to draw other functions envelope)
