A space time model is developed on a code division multiple access system, then based on the model an algorithm is proposed for estimating the directions of arrival (DOA's) of signals received from desired users. The relationship of the subspace of the received signal and the spreading code of the desired user is used to provide unique estimates even when the number of required DOA's exceeds the number of antenna array elements. This scenario is well known to cause conventional direction finding algorithms...
