2014 IEEE. In this paper, we examine the impact of antenna correlation on transmit antenna selection with receive maximal ratio combining (TAS/MRC) in multiple-input multiple-output multiuser network (MUN-MIMO) with single source, M destinations with underlay spectrum sharing over Nakagami-m fading environment. The secondary network under consideration is equipped with multiple correlated antennas at each node. The primary networks composed of L primary users (PUs) equipped with multiple correlated antennas. For the underlay spectrum sharing transmission, the transmit power condition of the proposed MU spectrum-sharing system is limited by peak interference temperature limit on the primary networks and the maximum transmission power at the secondary network. In particular, we derive an exact expression for the outage probability and SER of the proposed system. To gain further insights, simple asymptotic expression for the outage probability and SER are provided to obtain the achievable diversity order and coding gain of the system.
