Abstract :
We consider multiuser detection using antenna array. We use both the EM algorithm and its modified version, known as the space-alternating generalized expectation-maximization (SAGE) algorithm, to iteratively estimate the direction of arrival (DOA) and the transmitted symbols for each user of the CDMA system
