AB - This correspondence presents the channel capacity analysis of maximal-ratio combining with transmit antenna selection (TAS/MRC) in frequency-flat Nakagami-m fading channel with variable power and rate allocation techniques. In this paper, we evaluated exact closed-form expressions of channel capacity for TAS/MRC under different adaptive transmission techniques (1) optimal simultaneous power and rate allocation (opra) (2) optimal rate allocation with constant transmit power (ora) (3) channel inversion with fixed rate (cifr) and (4) truncated version of (cifr). An exact closed-form expression for channel capacity has been derived in uncorrelated Nakagami-m fading channels with single infinite series of tabulated function while the fading index is a real value. Numerical results illustrate the impact of fading severity on the channel capacity and outline the performance characteristics between the distinctive allocation schemes.
