Information rate of multi-antenna spectrally-efficient FDM communication

Abstract

The envisioned future Fifth Generation (SG) communication systems need to provide high data link throughputs to support the emerging wireless applications. In order to achieve more efficient use of bandwidth, non-orthogonal communication schemes have been considered to be essential. This paper focuses on extending the non-orthogonal spectrally-efficient frequency-division multiplexing (SEFDM) transmission into transmission over multiple-input-multipleoutput (MIMO) channels. Then, we derive corresponding capacity formulas to evaluate the achievable information rate of the considered SEFDM-MIMO channel. Furthermore, for different continuous-time modulation pulses, we evaluate the capacity of the SEFDM-MIMO channels.
