Abstract
The uplink of a space-time block coded multicarrier modulation code division multiple access (MC-CDMA) system equipped with a uniform linear array (ULA) at the base station in macrocell is studied and the base station antenna array is considered largely correlated because of insufficient antenna spacing and lack of scatterings. Under the circumstances, a blind decoder that provides closed-form solutions of both transmitted symbol sequences and directions of arrival (DOAs) for multiple users is developed without uplink space-time vector channel estimation. In particular, the decoder has a desirable property of being automatically paired between the transmitted symbol sequence of an individual user and corresponding DOA, which eliminates performing time-consuming joint diagonalization operations of many matrices [1] and thus saves computation cost. Computer simulations show the proposed receiver outperforms the conventional MMSE receiver based on channel estimation [2,3].
