Approximate symbol error rate (SER), outage probability, and rate expressions are derived for receive diversity system employing optimum combining when both the desired and the interfering signals are subjected to Rician fading, for the cases of equal power uncorrelated interferers, unequal power interferers, and interferer correlation. The derived expressions are applicable for an arbitrary number of receive antennas and interferers and for any quadrature amplitude modulation constellation. Furthermore, we derive a simple closed-form expression for SER in the interference-limited regime, for the special case of Rayleigh faded interferers. A close match is observed between the SER, outage probability, and rate results obtained through the derived analytical expressions and the ones obtained from Monte Carlo simulations. © 1967-2012 IEEE.

Analysis of Optimal Combining in Rician Fading With Co-Channel Interference

IEEE Transactions on Vehicular Technology

Secure outage probability and strictly positive secrecy capacity (SPSC) expressions are derived for single-input multiple-output systems over κ-μ shadowed fading channels. Also, a novel approximation for the SPSC is derived in terms of a single Gauss hypergeometric function. A close match is observed among the results obtained through the derived analytical expressions, the approximation, and Monte Carlo simulations. © 1997-2012 IEEE.

Secrecy Capacity of κ-μ Shadowed Fading Channels

The coverage probability (CP) and the average rate expressions when fractional frequency reuse (FFR) or soft frequency reuse (SFR) schemes are employed in single-input-multiple-output (SIMO) network are derived when the interferers undergo correlated Rayleigh fading. It is analytically shown that both the CP and the rate are higher in the presence of the correlated interferers (when the interferers are positively correlated) when compared with the case where the interferers are independent. It is also shown that the impact of correlation on SFR is more when compared with FFR, and it decreases with an increase in the power control factor. We show that the average rate achieved by FFR is higher when compared with the SFR in SISO networks for both the independent and correlated cases. However, the situation is reversed for SIMO networks. The impact of large-scale fading has also been briefly studied. © 2015 IEEE.

Impact of correlated interferers on coverage and rate of FFR and SFR schemes

In this paper we deduce some tight Tuŕan type inequalities for Tricomi confluent hy- pergeometric functions of the second kind, which in some cases improve the existing results in the literature. We also give alternative proofs for some already established Tuŕan type inequalities. Moreover, by using these Tuŕan type inequalities, we deduce some new in- equalities for Tricomi confluent hypergeometric functions of the second kind. The key tool in the proof of the Tuŕan type inequalities is an integral representation for a quotient of Tricomi confluent hypergeometric functions, which arises in the study of the infinite divisibility of the Fisher-Snedecor F distribution. ©2016 Akadémiai Kiadó, Budapest.

Turán type inequalities for confluent hypergeometric functions of the second kind

Analytical evaluation of outage probability (OP) and capacity for κ-μ and η-μ fading channel distributions, which model line-of-sight and non line-of-sight propagation effects, respectively, has been in focus lately. We derive an approximate closed form expression for OP and a simple expression for capacity in terms of hypergeometric functions, when the user experiences κ-μ fading and interferers experience η-μ fading with arbitrary parameters. Simulation results are presented along with analytical evaluation results, which prove that the approximations made for analytical evaluation are tight. © 1997-2012 IEEE.

Analysis of outage probability and capacity for κ-μ/η-μ faded channel

Symbol error rate (SER) performance has been analyzed for a receive diversity system in the presence of multiple interferers and noise over fading channels. Both unequal power interferers and correlated interferers have been considered. The derived approximate SER expressions are easy to evaluate and are applicable to any QAM constellation and arbitrary number of receive antennas and interferers. Further, the impact of correlation between interferer channels is studied and it is shown that correlation behaves like partial interference alignment. © 1997-2012 IEEE.
