Abstract
In this article, we focus on the downlink direction of cellular multiuser multiple-input, multiple-output (MIMO) systems based on orthogonal frequency division multiplex (OFDM) waveforms. Our target system is operated in the frequency division duplex (FDD) mode, while all base stations (BSs) use the same frequency spectrum for downlink transmission. State-of-the-art literature proved that the system performance is mainly limited by the existing cochannel interference (CCI). Hence, mitigating these effects would improve the achievable system throughput beyond current benchmarks of cellular systems.
