Abstract :
This paper presents a solution for direction-of-arrival (DOA) estimation in a IS-95 reverse channel environment using the so-called EM-algorithm. Simulations show a performance similar and sometimes better when compared with other methods such as delay-and-sum, Capon, MUSIC and ESPRIT. The performances of all these methods are then compared with the Cramer-Rao bound
