Abstract
The channel capacity and probability of outage results for optimum power and rate adaptation OPRA and truncated channel inversion with fixed rate TIFR schemes over correlated diversity branch obtained so far in literature are applicable only for m ≥ 1 This paper derived closedform expressions for the average channel capacity and probability of outage of dualbranch maximal ratio combining MRC over correlated Nakagami05 m 1 fading channels This channel capacity and probability of outage are evaluated under OPRA and TIFR schemes Since the capacity and probability of outage expressions of dualbranch MRC under OPRA and TIFR schemes contain an infinite series bounds on the errors resulting from truncating the infinite series have been derived for both average channel capacity and probability of outage The corresponding expressions for Nakagami05 fading are called expressions under worst fading condition with severe fading Finally numerical results are presented which are then compared to the capacity and probability of outage results that previously published for OPRA and TIFR schemes It has been observed that OPRA provides improved average channel capacity and probability of outage as compared to TIFR under worst case of fading It is also observed that probability of outage under TIFR scheme is not improved adequately than the probability of outage under OPRA even as employing diversity
