基于MATLAB的QPSK通信系统仿真源码，信道误码率等(MATLAB-based simulation of communication systems QPSK source, channel bit error rate)

Spectrum sensing is one of the core technologies for cognitive radios (CR) that in this project used Pd vs Pm

EMD 算法，消除信号趋势项，可以作为信号预处理的部分(Part of the EMD algorithm to eliminate the signal trend term, can serve as a signal preprocessing)

matlab编程与应用，非常实用和完整的工具书。希望大家能够喜欢。(Matlab programming and application of practical and very complete tool. Hope that we can like.)

音频信号降采样程序 支持48k->8k 24k->8k 8k->1k 的降采样.实现方法,先做低通滤波,再做采样点抽取.低通滤波起使用67点FIR,系数由matlab使用窗函数法生成 (Audio signal down-sampling procedures to support the 48k-)

二微时域有限差分的matlab模拟 二微时域有限差分的matlab模拟(two- finite-difference time-domain simulation of the two-Matlab finite-difference time-domain simulation of Matlab)

off line FX-LMS algorithm to reduce noise from primary path

FDTD基本代码，计算电场和磁场时间更新(FDTD basic code, calculate the electric and magnetic time updates)

傅里叶变换功能的实现，虽然是非常见得的频率成分，但是还是实现了基本的傅里叶变换功能，并不是matlab自带的fft函数。实现了频谱分析可视化。(Fourier transform function, although it is very frequency components appear, but still achieve the basic function of the Fourier transform, comes not matlab fft function. Achieve a spectral analysis visualization.)
