Abstract :
In this paper, a direction of arrival (DOA) estimation algorithm is proposed for uplink MC-CDMA system with antenna array. By utilizing the orthogonality of spreading codes and frequency diversity of MC-CDMA the users´ signals are separated and enhanced, and the multiple access interference (MAI) is suppressed. After that the conventional subspace based DOA estimation is applied to estimate the DOAs of users´ signals. Simulation results show the efficiency of the proposed algorithm.
