Delay Estimation of Multipath in Asynchronous DS-CDMA System
Li Jin · Fudan xuebao. Ziran Kexue ban · 2003
With antenna array at base station of DSCDMA system,TOA estimation can be accomplished by using improved Direct Matrix Inversion (DMI) algorithm for radiolocation technology. It can distinguish each main multipath of every user. The accuracy will reach less than one chip. The influences of some parameters in this TOA estimation have been discussed. After taking the shortest TOA as the main path,TOA tracking can be realized by using RLS blind algorithm.
