Filter bank multicarrier (FBMC) modulation has many nice features compared with conventional cyclic prefix-based orthogonal frequency multiplexing (CP-OFDM) and has been considered as a promising waveform candidate for future 5G wireless communication. Combining FBMC with multiple-input multiple-output (MIMO) technology may achieve high data rate. In this paper, we propose the K-Best algorithm based...
In this paper, we perform transmit antenna selection to improve the energy efficiency of large scale MIMO systems. We first derive a good approximation of the distribution of the mutual information in this antenna selection system. It shows that channel hardening phenomenon is still retained as full complexity with a large number of available antennas, though the number of actually used antennas can...
This paper considers the implementation of Tomlinson-Harashima (TH) precoding for multiuser MIMO systems based on quantized channel state information (CSI) at the transmitter side. Compared with the results in , our scheme applies to more general system setting where the number of users in the system can be less than or equal to the number of transmit antennas. We also study the achievable average...
