高阶累积量工具箱参数设定
下了高阶累积量的工具箱,但是有些参数不会设定,function y_cum = cum4est (y, maxlag, nsamp, overlap, flag, k1, k2)
%CUM4EST Fourth-order cumulants.
% Should be invoked via CUMEST for proper parameter checks
% y_cum = cum4est (y, maxlag, samp_seg, overlap, flag, k1, k2)
% Computes sample estimates of fourth-order cumulants
% via the overlapped segment method.
%
% y_cum = cum4est (y, maxlag, samp_seg, overlap, flag, k1, k2)
% y: input data vector (column)
% maxlag: maximum lag
% samp_seg: samples per segment
% overlap: percentage overlap of segments
% flag : 'biased', biased estimates are computed
% : 'unbiased', unbiased estimates are computed.
% k1,k2 : the fixed lags in C3(m,k1) or C4(m,k1,k2); see below
% y_cum : estimated fourth-order cumulant slice
% C4(m,k1,k2)-maxlag <= m <= maxlag
%Note: all parameters must be specified
这是工具箱前的参数,我做的是信号检测,用四阶累积量算法,不知道该怎样设定参数?
maxlag,overlap,
flag,samp_seg,k1,k2,
