PCM编码解码matlab 代码

这是16QAM的仿真，带GUI界面，很好用的。(This is 16QAM simulation, with GUI interface, very useful.)

说明：  Taming the Complexity of mm-Wave Massive MIMO Systems: Efficient Channel Estimation and Beamforming

说明：  QPSK调制信号通过高斯信道后输出BERvsSNR图像(QPSK modulated signal through Gaussian channel)

This book is very nice for designing a wireless network which describes in details how the wireless systems are designed.

说明：  SCMA系统中的PM-MPA检测，信道采用瑞利信道，迭代次数为6(For PM-MPA detection in SCMA system, Rayleigh channel is adopted and the number of iterations is 6)

传输屏幕到远程电脑并显示,很不错的易语言源码,易爱好者可以下载使用()

说明：  64qam调制解调的Matlab程序仿真代码，对研究64QAM很有帮助(64qam modulation and demodulation process of the Matlab simulation code, very helpful for research 64QAM)

说明：  2. 关于无线信道的多普勒谱，请回答以下问题： (1) 在某些无线信道中，多普勒频移会引起无线信道输出信号的混叠。请描述产生混叠的各种原因； (2) 无线信道中的多普勒谱有一种经典谱(classic spectrum)，请解释产生这种谱形状的机理； (3) 请用Simulink工具编写代码(S-Function方式)，产生一单径瑞利信道，其多普勒谱为经典谱，其中移动速率为120km/h。并请描述：自己用计算机产生的经典谱是正确的依据。(2. Regarding the doppler spectrum of the wireless channel, please answer the following questions: (1) in some wireless channels, doppler frequency shift will cause aliasing of the output signals of the wireless channel.Describe the various causes of aliasing; (2) there is a classic spectrum in the doppler spectrum in the wireless channel, please explain the mechanism of producing this spectrum shape; (3) please use Simulink tool to write code (s-function mode) to generate a single-path Rayleigh channel, whose doppler spectrum is the classical spectrum, in which the moving rate is 120km/h.And please describe: your own computer generated classical spectrum is the correct basis.)

用 MATLAB 对基带数字通信系统进行仿真。整 个系统模拟了发送和接收的全过程。其中调制部分采用 16QAM，并且采用基带传输(Using MATLAB for baseband digital communication system simulation. The system simulates the entire process of sending and receiving. Where the modulation part is 16QAM, and using the base band transmission)

基于matlab实现的循环谱估计算法，可以对具有循环平稳特点的信号进行参数估计(Matlab-based spectral estimation algorithm to achieve the cycle, you can have the characteristics of the signal cyclostationary parameter estimation)
