“…Here, E s and N 0 denote the average symbol energy and the one‐sided power spectral density of additive white Gaussian noise at each receive antenna, respectively. The SNR statistics related to the instantaneous SNR of each branch for JTRAS/OSTBC scheme have been obtained in (also in and ) as , x ≥ 0, and , x ≥ 0, respectively. Here, , Re ( u ) > 0 is the Gamma function [, (8.310.1)] and , Re ( u ) > 0 is the incomplete Gamma function [, (8.350.1)].…”
