Abstract
In this paper, the performance of a multiuser distributed spatial multiplexing system is analytically investigated. The system operates under a Nakagami-m fading environment. All the users, equipped with single antennas, are simultaneously transmitting their streams to a multi-antenna receiver. Zero-forcing is applied along with successive interference cancellation as a means for efficient detection of the received streams. New exact closed-form expressions with regards to some important performance metrics, namely, outage probability and ergodic capacity of each stream are presented. Both the analytical expressions and the simulation results show the impact of channel severity and scale of antenna array to the overall system performance. A particular emphasis on the scenario of the emerging massive multiple input-multiple output systems is provided.
