Cramér-Rao Lower Bound in the Estimated Time of Arrival in a Rice Channel

Blog Article

This document Recliner with Power 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 Beds - Bed Headboards and Footboards 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.
