摘要：
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.
