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)

为的x,y,z的长度相同
N是周围围点的数量。默认值
为N= 100。
Ø 定义了矩阵圆柱generatix(圆圈)椭圆
表面。其内容以0和1之间的值,并适用于
小学和中学的母线轴。值的defeault
Ø =的(长(x),2)。
矩阵X,Y,Z轴确定圆柱面,冲浪(的X,Y,Z)的显示器
圆柱面。( [X,Y,Z]=cylinder2(x,y,z,r,N,o)
Vectors x, y, z define the central line of cylindrical surface
and vector r defines the radius of cylindrical surface, and has
the same length as x, y, z.
N is the number of points around the circumference. The default value
is N = 100.
Matrix o defines ovality of the generatix (circle) of cylindrical
surface. Its elements take values between 0 and 1 and apply to the
primary and secondary axis of generatrix. The defeault values are
o=ones(length(x),2).
Matrices X, Y, Z define the cylindrical surface, surf(X,Y,Z) displays
the cylindrical surface. )
