DVB-T-TimingaChannelEstimation
DVB-T 2k模式定时估计Matlab仿真。重新修改了程序。包括DVB-T信号产生,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,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。
信道估计利用DVB-T导频,LS估计,导频位置的时间插值,非导频位置频率插值,非常有效。
该程序经过多次运行无误,不足之处在于变量使用不规范,注释简单,读程序很费劲哈。
其特点是均采用经典算法,简单有效为主,对初学者很有帮助滴。(DVB-T 2k signal, timing estimation, channel estimation)
