Abstract

An approximate maximum likelihood method for joint estimation of time delays and directions-of-arrival for direct-sequence code-devision multiple-access systems over multipath Rayleigh fading channels is presented. To reduce the computational complexity, the multi-dimensional maximisation problem is transformed into two simple one-dimensional maximisation problems using an iterative scheme. To illustrate the performance, simulation results are compared with Cramer-Rao bounds.
