In this article, we investigate the performance of dual-hop amplify-and-forward multiple-input multiple-output relaying system with orthogonal space-time block code transmissions over doubly-correlated Nakagami-m fading channel, where the source, relay, and destination terminals are all equipped with multiple antennas. For two different CSI-assisted(More)
Multi-cell MIMO technique theoretically promises large improvement in spectral efficiency and fairness in cellular networks and is regarded as the key enabling technique for solving the troublesome issue of inter-cell interference. To evaluate its practical performance in the cellular network, we have implemented the real-time downlink multi-cell MIMO trial(More)
—MIMO-OFDM is widely considered as a promising framework of the future broadband mobile communication systems due to its prominent advantages such as high spectral efficiency, low-complexity equalization for multi-path fading, and sufficient exploiting of the spatial degree of freedom. However, an inherent drawback of OFDM, i.e., high sensitivity to(More)
