Constrained Adaptive Time Delay Estimation Based on Cyclostationarity
Chen Gong · Jisuanji gongcheng · 2011
Taking into account the influence of the non-stationary interference in other channels and stationary noises,a constrained adaptive time delay estimation algorithm based on cyclostationarity is proposed.This algorithm is based on the cyclostationarity of the signals,it can refrain the interference of disturbances and noises effectively,and it is useful when the noises are spatially correlated.It can attain time delay which is not an integer multiple of sampling interval accurately and directly in low signal-to-noise ratio environment,and its computation load is much smaller than that of interpolation method.Simulation results demonstrate the effectiveness of the algorithm.
