init_tdftaf.m

卡尔曼滤波器设计的一个例子

% [W,w,x,d,e,y,p]=init_tdftaf(L,W0,x0,d0)
%
%    Creates and initializes the variables required for the 
%    Transform Domain Fault Tolerant Adaptive Filter (TDFTAF).
%    TDFTAF contains R redundant coefficients to guarantee that 
%    the filter will recover after the occurrence of a partial 
%    hardware failure during operation.
% 	
% Input Parameters [Size]:: 
%    L   : number of filter coefficients
%    R   : number of redundant coefficients
%    w0  : initial T-domain coef. vector [L+R x 1] 
%    x0  : initial input samples vector [L x 1] 
%    d0  : initial desired sample [1 x 1] 
% Output parameters [default]::
%    W   : initialized T-domain coef. vector [zeros]
%    w   : initialized time-domain coef. vector [zeros]
%    x   : initialized input vector [white noise]
%    d   : initialized desired sample [white noise]
%    y   : Initialized filter output
%    e   : initialized error sample [e = d - y]
%    p   : initialized power estimate
