Using Decision to Suppress MAI of Downlink Positioning Signal in CDMA Mobile Communications Systems
Gong Yao · 2003
In this paper we first analyzed the effect of MAI in CDMA mobile communication when using downlink signal to position mobile station,and then proposed an algorithm through mathematical derivation.Using this algorithm we can calculate the reliability of the estimation of Time of Arrive of downlink signal,get rid of the result that is not reliable,and improve the veracity of location estimation.The algorithm is very simple .Simulation results demonstrate that the proposed algorithm can reduce error of location estimation very greatly.
