Abstract:

Multiple input multiple output architecture is one of the most promising techniques to improve the quality and capacity of future wireless communication systems. In this paper we proposed an improved layered space-frequency scheme for the broadband MIMO-CDMA systems. The proposed scheme opens the way of detecting multi-antenna signals in the frequency domain. Simulation results show that the proposed layered space-frequency scheme can obtain better tradeoff between performance and complexity than conventional ones.

Key words: multiple input multiple output, layered space-frequency scheme, single carrier frequency domain equalizer
