An effective algorithm is proposed to estimate multipath time delays in a CDMA chip under low SNR environment. Firstly, a power delay profile of multipath is constructed which can restrain effect of noise. Then the estimation algorithm that has super resolution is deduced based on the function. A detailed estimation process and analysis of the performance of this approach are given. Finally, comparsion and performance simulation demonstrate that the method can effectively estimate the delay of multipath in a CDMA chip under low SNR environment.
