Adaptive time delay estimation based on cyclostationarity
Geng Xiao-min · Microcomputer Information · 2008
A new adaptive time delay estimation method based on the cyclostationary property of the source signal is proposed in this paper.When the carrier frequency or keying rate of the source signal is different from those of interfering signal,non-stationary interference and spatially correlated noises can be suppressed effectively by using the cyclostationarity of signal.Simulation examples are given to demonstrate that the new method has better performance than the parametric approach to time-delay estimation.
