Channel Capacity of Dual-Branch Maximal Ratio Combining under Worst Case of Fading Scenario
Authors: ,
Abstract: The worst case fading scenario can be represented by Nakagami-0.5 distribution, which is a special case of Nakagami- fading distribution. Under Nakagami-0.5 fading distribution closed-form expressions have been derived for the average channel capacity using uncorrelated dual-branch maximal ratio combining (MRC). This channel capacity is evaluated under Optimum Power with Rate Adaptation (OPRA) and Truncated Channel Inversion with Fixed Rate transmission (TIFR) schemes. And Numerical results of the average channel capacity under OPRA and TIFR have been presented and compared. It has been observed that OPRA provides higher capacity than TIFR under worst case of fading.
