Abstract :
We propose a new space-time minimum variance (MV) receiver with an antenna array for asynchronous code division multiple access (CDMA) systems. According to our simulation study, the proposed receiver shows superior performance to the single antenna MV receiver even in the presence of a non-zero angular spread. Furthermore, the performance of the proposed algorithm is insensitive to the degree of the angular spread or the spacing between antenna elements
