Simple PDF of the sum and maximum of non‐identical fluctuating two‐ray variates

Abstract

Abstract In this letter, probability density function (PDF) of the sum and maximum of non‐identical fluctuating two‐ray (FTR) variates are derived in terms of the power and exponential functions. To this effect, novel mathematically tractable expressions of the outage probability (OP) and average bit error probability (ABEP) for both the maximal ratio combining (MRC) and selection combining (SC) diversity receptions are provided. The numerical results are affirmed by the Monte‐Carlo simulations for different scenarios.
