Abstract

This document introduce a Rice mobile channel model suitable for the study of parameters of interest that modifies the accuracy in the estimation of the Time Of Arrival (TOA) for the signal emitted from a mobile station, operating in a DS-SS. This work shows the receiver performance in terms of the available number of channel estimates, the number of sensors in the antenna array and the type of signal source when sampling rate is higher than the chip rate. Received signal is modeled from time-space stochastic distributions and the cases of partially coherent distributed sources as well as fully coherent distributed sources and fully incoherent distributed sources are considered.
