MC-CDMA系统的简要介绍和系统的MATLAB 仿真性能实现(the generalized analysis of MC-CDMA system and realization using MATLAB code.)

A project in university

说明：  对比了dv-hop基本算法，和加入pso后得算法。由于结果是随机产生的，不能保证每次得结构都能提高，但大部分时候，比基本算法得定位准确度好。(DV hop algorithm is compared with PSO algorithm. Because the results are generated randomly, it can not be guaranteed that every time the structure can be improved, but most of the time, the positioning accuracy is better than the basic algorithm.)

本文详尽阐述了如何在matlab环境下进行MIMO ofdm编程。符合国际标准(This paper elaborates how the MIMO ofdm matlab programming environment. Compliance with international standards)

说明：  本程序是MIMO-OFDM系统的信道估计程序,包括导频设计,信道建模呵常见的信道估计方法,对初学者有用(This program is the system MIMO-OFDM channel estimation process, including the pilot design and channel modeling Oh common channel estimation method, useful for beginners)
