%X The uplink of a space-time block coded MC-CDMA system equipped with a uniform linear array at the base station of macrocellular is studied. A blind estimation algorithm is proposed to provide the closed-form solutions of both the transmitted symbol sequences and the Directions Of Arrival (DOA) for multiple users without determining the space-time vector channels. An auxiliary matrix including both the coded symbol sequences and DOAs is derived, on which the eigen decomposition is performed to obtain the DOAs of different users. Then, the algorithm exploits the structure of space-time block coding in combination with the finite alphabet property of transmitted symbols to estimate the original symbol sequences for all active users. The computer simulations demonstrate the effectiveness of the proposed scheme.
