Achievable rate of hybrid precoding for hardware impaired MIMO underground mine channel

Hybrid precoding has become a well-accepted approach to enhance the achievable rate in the adverse millimeter-Wave (mm-Wave) multiple input multiple output (MIMO) channels. Transceiver impairments are inherent to any practical communication system, yet they are generally omitted when investigating the performance of wireless systems. More particularly, for the case of mm-Wave underground channels, no study has been reported yet. To overcome this limitation, in this letter, a new architecture encompassing hybrid precoded mm-Wave MIMO structure, in which the hardware impairments have been incorporated in the transceiver processing, is presented. Furthermore, the geometrical one ring model is applied on the underground mm-Wave measured channel on which the architecture is tested.
