PSK

已知信号的m(t)dsb-am调制 ~~~~~~~~~~~~~~~~~~~~~~~~~~··(dsb-am)

说明：  DSP入门：应用傅里叶变换对信号进行频谱分析(DSP basis: Implement of Fourier Transfer to analysis signals spectrum)

说明：  维纳噪声抑制 分辅助观测数据中漏入观测信号和不漏入观测信号两种情况讨论(Wiener noise suppression sub-assisted observational data leak into the observation signal and the signal does not leak into the observation to discuss two cases)

离散小波变换，包括各层分解，消除了边界效应等问题(DWT，including every layer)

应用Matlab产生各种数字调制信号以及在AWGN下的传输结果。包括AM，QPSK，BPSK等(Application of Matlab have a variety of digital modulation signal and transmit the results under AWGN. Including AM, QPSK, BPSK, etc.)

addition of white gaussian noise

说明：  此程序是用矩阵的方法解决一些常见问题，比如说学生成绩排序筛选等问题，希望对一些人有用。(This program is a matrix methods to solve some common problems, such as student achievement to sort filter and so on, want to be useful for some people.)

扰码生成， matlab编程， 可以直接使用(scramble code matlab)

说明：  在多用户干扰情况下，仿真IR-UWB系统的性能。(In the case of multi-user interference, simulation IR-UWB system performance.)

一些lms和nlms的程序，比较适合初学lms的同学，上传上来跟大家一起参考学习(lms and nlms)
