Throughput analysis using opportunistic feedback, capture effect and MRT in Nakagami-m fading

The downlink throughput of independent and correlated Nakagami-m fading transmission employing MRT is studied in this paper. Two typical correlation models are considered: (i) equi-correlation and (ii) exponential-correlation. Throughput for independent and identically distributed Nakagami-m fading is also obtained and employed to validate results for the two correlated cases. Compact expressions of the downlink throughput for three separate cases are derived which can be readily implemented in software packages such as MATLAB and Mathematica. Mathematical mistakes in the literature are identified and corrected. Numerical simulation is given for various scenarios.
