基于巴特沃思滤波器的50Hz工频险波器

首先一个是基于JAKE模型的多径衰落信道模型及性能分析。另外一个是OFDM系统中基于上述信道模型的性能分析。(JAKE first model is based on a multipath fading channel model and performance analysis. Another system is the OFDM channel model based on the above analysis of the performance.)

DVB-T 2k模式定时估计Matlab仿真。包括导频和TPS插入，瑞利多径信道衰减，高斯噪声加入。 定时估计的粗定时用极大似然法，利用循环前缀特征，不需要专门训练序列。细定时用分散导频。首先确定导频模式，再通过相邻导频相关确定定时偏差。此方法适用于瑞利多径信道，高斯信道，也适用于莱斯多径信道。(DVB-T 2k timing estimation.)
