Abstract
In wireless communications, mobiles emit signals that arrive at a
base station via multiple paths. Estimating each path's angle-of-arrival
(AOA) and propagation delay is necessary for several applications, such
as mobile localization for emergency services. We propose a novel
subspace approach to estimate the AOA and delays of multipath signals
from digitally modulated sources arriving at an antenna array. Our
method uses a collection of estimates of a space-time vector channel.
The Cramer-Rao bound (CRB) and simulations are provided
