“…In [ 29 ], the assumed model was used to assess the communication assistance via reconfigurable intelligent surfaces in terms of the bit error rate, outage probability and ergodic capacity. A performance analysis of the communication systems with the low-resolution analog-to-digital converters (ADC) functioning in the presence of the complex Nakagami-m fading was carried in [ 30 ] in terms of the outage probability and the total sum-rate capacity of the MIMO system and in [ 31 , 32 ], in terms of the energy distortion coefficient for the energy-based signal detection.…”

This research studies the problem of a joint capacity/capacity reliability analysis of the multiuser multi-input multioutput (MIMO) system functioning in the presence of generalized multipath fading. The study presents the derived results of the closed-form analytical statistical description of the ergodic sum-rate capacity, the capacity reliability and the capacity’s higher-order statistics in the case of complex Nakagami-m distributed channel transmission coefficients. A numerical verification of the derived expressions was performed, and it demonstrated excellent correspondence with the simulation. The system performance was evaluated with the help of a numerical analysis of the joint first- and second-order statistics description, depending on the channel and system parameters. The results demonstrated several peculiarities, e.g., the existence of a specific extremum of the capacity reliability for small-sized MIMO systems, its opposite behavior (in terms of the varying number of antenna elements) for heavy and light fading, and the existing asymptotic regions of the system and the channel parameters.
