Abstract

In this paper, we introduce a new channel allocation scheme for up-link code division multiple access (CDMA)-based multi-user multiple-input multiple-output (MIMO) systems. In such a system, different users are treated as multiple antennas and space-time multi-user detection algorithms are used at the receiver to separate users sharing the same channel. In our allocation scheme, users are allowed to share multiple up-link codes simultaneously. This improves the overall up-link system capacity and fairly equalizes the bit error rate (BER) performance of different users
