基于DFT的MIMO-OFDM系统的信道估计算法研究代码
说明: MIMO系统仿真 MIMO技术可W极大地提升系统吞吐量和有效抵抗多径衰落的影响,被视作LTE的核也技术之一。信号检测模块又是MIMO系统中非常重要的一步,因为接收端收到的信号是经历了无线信道衰落影响的信号,与发送端发送的初始值之间差距较大,因此,在接收端首先应进行信道估计求出信道矩阵H,然后根据该信道矩阵的信息,从接收端还原出发送信号。因此,在MIMO系统中信号检测直接彰响着系统系能的提升。本章将先介绍高移动性MIMO无线信道的建模方法(simulation of MIMO-OFDM communication system)

FrequencyHoppingTechnology
在无线通信中使用跳频技术是军事通信中最主要的抗干扰手段之一, 而如果系统中能使用合适的中心频率可以快速跟踪跳频变化的带通滤波器将可以明显改善系统的抗干扰性能。文中从实际应用出发, 比较了几种可用于实现带通滤波器快速变频的方案, 选择了简单、实用的开关电容阵改变带通滤波器中心频率的方案(The use of frequency hopping in wireless communication technology is the most important anti-jamming in military communications, one of the means, and if the system can use the appropriate center frequency can be fast-tracked changes in frequency-hopping band-pass filter will be able to significantly improve the system anti-jamming性能. This paper from the actual application, the comparison of several band-pass filter can be used to achieve the rapid conversion of the program, choose a simple, practical switched capacitor array to change the center frequency of band-pass filter program)

在Microsoft Visual C++软件环境下,用C++
语言实现整个仿真。将整个产生系统分为C/A码产生,信号产生,量化三个模块,经过编写和调制实现产生的基本功能,即输入导航电文及控制数据,例如 选取卫星信号,多
普勒频移,采样周期。最后可以得到加入服从高斯分布的噪声信号的数字离散中频信号。
(We use the C++ language to archive the simulation in the Microsoft Visual C++
circumstance. The entire generating system is divided into three parts,including C/A Code, Signal Generating and Quantizer. After writing codes and checking and
confirming, I archive the basic functions. If you input the guiding codes and controldata like satellite selecting signal, Doppler frequency movement, sampling period, at last you can get the digital middle frequency signals with gauss distributing noise)
