Abstract

Multiple-input multiple-output (MIMO) concept has been recognized as one of the key approaches for providing required bandwidth efficiency in the evolution of 3G wireless systems. However, the choice of the particular MIMO transceiver scheme is still an open issue and it is under intensive discussion in standardization bodies. In this paper we tackle the topic of the choice of the appropriate MIMO scheme for the long term evolution of 3G systems. We show that, among the considered schemes, quasiorthogonal matrix modulation approach is the most appealing one in 2 times 2 and 4 times 2 configurations
