Abstract

To meet the requirements of beyond 5G networks, the significant amount of unused spectrum in sub-TeraHertz frequencies is contemplated to realize high data-rate wireless communications. Yet, the performance of sub-TeraHertz systems is severely degraded by strong oscillator phase noise. Therefore, we investigate in this paper the use of multiple-inputs multipleoutputs (MIMO) systems with non-coherent detection receivers to achieve high spectral efficiency communications robust to phase noise. Based on energy detection receivers, we derive the maximum likelihood symbol detection decision rule and compare it to the standard Euclidean receiver. The performance of the detectors is assessed through numerical simulations on a realistic scenario modeling an indoor wireless link. Results demonstrate that sub-TeraHertz systems with high spectral efficiency can be implemented on low complexity and low power architectures using MIMO systems and energy detection receivers.
