Abstract

In this paper the code-division multiple-access (CDMA) multiple-input multiple-output (MIMO) systems with space-time block code (STBC) are investigated. Both the forward-backward averaging technique and the eigenspace: technique are proposed to enhance the system performance. Moreover, we present a subspace-based channel estimator which utilizes the space-time coding property to improve the performance of channel estimator. Then the performance analysis using the first order perturbation theory is derived. Computer simulations are given to demonstrate the effectiveness of the channel estimation and receiver design for the STBC-based CDMA systems
