Millimeter-Wave (mmWave) systems recently attracted attention as one of the key enablers for the Fifth Generation (5G) networks. The small wavelength at mmWave frequencies enables deploying massive Multiple Input Multiple Output (MIMO) antenna arrays at the transmitter and receiver sides with reasonable form factor. However, massive MIMO mmWave systems suffer from a lot of practical limitations, specifically due to channel and hardware characteristics at such high frequencies. In this poster we propose multiple solutions to design a realistic massive MIMO cellular system that takes into account the imposed limitations and achieves considerable gains in terms of spectral efficiency.
