LDPC__64QAM仿真程序___matlab

在做毕业设计时编写的程序，主要内容是高铁环境下LTE系统的切换算法研究，源码中含scm信道模型。(a simulation about handover in LTE under high-speed railway station environment, which involving scm channel model.)

turbo码的matlab仿真源程序,比较详细,包你满意()

频分复用信号的生成以及演示，与英文工具书匹配，很好用！(FDM signal generation)

这是一个关于数字通信原理的实验，特别适合大学生们，(This is a study on the principle of digital communication experiments, particularly suitable for students,)

2008年春季函授有关问题1 林厚从(Correspondence relating to the spring 2008 issue of 1 lam thick from the)

这是瑞丽衰落信道模型和莱斯衰落信道模型的代码。(This is the code of Rayleigh fading channel model and Rice fading channel model)

基于多径传输和多普勒频移的 瑞利（Rayleigh）信道的仿真 主要考虑不同条件下的仿真(Based on Multi-Drive transmission and Doppler frequency shift of the Rayleigh (Rayleigh) channel simulation main consideration different The simulation conditions)

OFDM(正交频率调制)实现多载波调制基本思想是将带宽信道分解成许多并行的窄子信道，是每个子信道的想干带宽，从而实现平稳衰落。搭建了完整的OFDM信道链路系统，运用三种不同的信道估计方法(LS信道估计、DFT信道估计、Improved-DFT信道估计)，并对AWGN理想信道和衰落信道误码情况进行了仿真和比较。(OFDM (Orthogonal Frequency Modulation) multicarrier modulation basic idea bandwidth channel is decomposed into a number of parallel narrow subchannels, each subchannel wanted bandwidth, in order to achieve a smooth fading. Build a complete OFDM channel link system, the use of three kinds of different channel estimated method (LS channel estimated, to the DFT letter Tao estimates, Improved-the DFT letter Road estimated), and AWGN ideal letter Road and fading channel bit error situation conducted a simulation and comparison .)

这是一个CD4067B的技术资料，希望对大家有帮助。(This is a CD4067B technical information, we hope to help.)
