OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术,实际上OFDM是MCM Multi-CarrierModulation,多载波调制的一种。其主要思想是:将信道分成若干正交子信道,将高速数据信号转换成并行的低速子数据流,调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开,这样可以减少子信道之间的相互干扰 ICI 。每个子信道上的信号带宽小于信道的相关带宽,因此每个子信道上的可以看成平坦性衰落,从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分,信道均衡变得相对容易。本程序实现OFDM与QPSK技术的比较(This program realization technology and the OFDM QPSK technology)

基于LMS算法的MATLAB仿真源程序
说明: 从信号估计和频谱分析的观点分析了LMS算法,提出了LMS算法应具有低通性能的观点,并给出了求取算法收敛因子的公式。(In this paper, the LMS algorithm is analyzed from the viewpoint of signal estimation and spectrum analysis. The viewpoint that the LMS algorithm should have low-pass performance is put forward, and the formula for calculating the convergence factor of the algorithm is given.)
