The Signal Noise Ratio(SNR)of CDMA2000 mobile station signal falls sharply in non-cooperative reception
considering the height of receiving antenna and power constrains of Near-Far effect. It is difficult to get the location parameters in the non-cooperative signal. Begin with theoretical model analysis
this paper presents a signal strength of arrival(SSOA)estimation algorithm based on data-aimed accumulation statistics. The algorithm principle has been deduced in detail
and the simulation has been carried out using real air signal. The results show that
the performance of proposed algorithm gets better with accumulation grows
and hardly changes with the frequency offset within the tolerance of CDMA2000 mobile station signal. It is better than cyclic spectrum amplitude algorithm
Data-Aimed Maximum Likelihood (DAML)algorithm and Decision-Directed Maximum Likelihood (DDML) algorithm when SNR remains below -10dB.
