Detection of sinosoidal signal in WGN with unknown frequency,amplitude,phase

这是我收集的几个通信基础理论的Matlab仿真实现，包括bpsk、qpsk、ofdm以及信号衰减和延迟的仿真。尽管不是我本人原创，但比较都经典(gggggggggggggg)

This code is about migration of seismic data.

Recteneald数值计算一书的所有源码和课件(Recteneald on a numerical calculation of all source and courseware)

运用小波的几种方法对信号进行去噪对比仿真效果(Simulation results are several ways to use wavelet signal de-noising comparison)

Determinant of the permutation matrix with rows ordered by p.

qpsk的调制解程序 包括在两种信道下的功率谱和星座图(qpsk the modem program includes two channels of the power spectrum and constellation)

HSB颜色空间的细胞分割，短小，实用，直接运行(The color space of HSB cell segmentation, short, practical, direct operation)

与其它高级语言相比较，MATLAB具有独特的优势：(1) MATLAB是一种跨平台的数学语言。(2) MATLAB是一种超高级语言。MATLAB平台本身是用C语言写成的，所以在编程效率，程序的可读性、可靠性和可移植性上远远超过了常规的高级语言。(3) MATLAB语法简单，编程风格接近数学语言描述，是数学算法开发和验证的最佳工具。(4) MATLAB计算精度很高。与其它语言相比，MATLAB对计算机内存、硬盘空间的要求也是比较高的。(Compared with other high-level languages​ ​ , MATLAB has unique advantages: (1) MATLAB is a cross-platform language of mathematics. (2) MATLAB is a super-high-level language. MATLAB platform itself is written in C, so the programming efficiency, readability, reliability and portability far more than the regular high-level language. (3) MATLAB syntax is simple, close to the mathematical language to describe the style of programming is a mathematical algorithm development and validation of the best tools. (4) MATLAB computing high accuracy. Compared with other languages​ ​ , MATLAB computer memory, disk space requirements are relatively high.)

几个有关通信系统的matlab程序,有关信号，包含：a,对抽样频率为90kHz的信号进行下抽样抗混叠滤波器设计的程序，b,信号抽样率转换的程序，c,通过补零内插对信号进行下抽样，分析抽样对信号频谱的影响的程序(Some matlab programs about communiction system,mainly about signal,a,program about filter to signal sampling without aliasing ,b,transfering signal sampling rate,c,zeros-added sampling,with its influence of phase-frequency。)
