“…However, the author points out that such representation presents certain computational challenges. In [6], Piboongungon et al investigated the average symbol error rate (SER) performance of both maximum ratio combining (MRC) and equal gain combining (EGC) receivers over GG fading channels. The authors used the moment generation function (MGF)-based approach [1] in the case of MRC receivers and the characteristic function (CHF)-based approach [7] for the EGC receivers.…”

Abstract-In this paper, we are interested in determining the cumulative distribution function of the sum of α − µ, κ − µ, and η − µ random variables in the setting of rare event simulations. To this end, we present a simple and efficient importance sampling approach. The main result of this work is the bounded relative error property of the proposed estimators. Capitalizing on this result, we accurately estimate the outage probability of multibranch maximum ratio combining and equal gain diversity receivers over α − µ, κ − µ, and η − µ fading channels. Selected numerical simulations are discussed to show the robustness of our estimators compared to naive Monte Carlo estimators.

“…Most of the other attempts fail to provide a closed-form expression for this cumbersome problem and only propose to tackle it by deriving approximate solutions that usually involve a truncation error. In [4], Piboongungon et al investigated the average symbol error rate (SER) performance of both maximum ratio combining (MRC) and equal gain combining (EGC) receivers over GG fading channels. The authors used the moment generation function (MGF)-based approach [3] in the case of MRC receivers and the characteristic function (CHF)-based approach [5] for the EGC receivers.…”

“…Previous papers concerning EGC diversity [2][3][4][5] (and references therein) assumed the received signal phase estimation to be perfect. Only three papers, [6][7][8], considered the influence of imperfect estimation of the received signal phase on the system performance.…”

“…Notice that the Nakagami-m, exponential, Weibull, one-sided Gaussian and Rayleigh distribution that are used for modeling multipath fading channels, as well as Gamma and Lognormal (as a limiting case) distributions that are used for modeling shadow fading are special instances of the generalized α − μ distribution [9,10]. Despite the fact that the α − μ distribution includes several widely used fading distributions as special cases, only two papers [4,5] considered the performance of EGC receiver in α − μ fading channel, and analysis in both papers was done under assumption of perfect cophasing. Unlike previously mentioned papers [2][3][4][5][6][7][8], where the uncoded signal detection was observed, in this paper we determine the average BER for both uncoded and low-density parity-check (LDPC)-coded BPSK and QPSK signals.…”

This paper studies the bit-error rate (BER) performance of partially coherent equal-gain combining reception of uncoded and low-density parity-check (LDPC)-coded binary and quaternary phase-shift keying signals over generalized α − μ fading channels. For the uncoded signal detection case the obtained numerical and simulation results illustrate the BER performance degradation due to the imperfect reference signal recovery, receiver unbalancing and fading. It is demonstrated that imperfect cophasing causes an irreducible BER performance. Furthermore, we design large girth quasi-cyclic LDPC code with high code rate, suitable for use in communications over generalized fading channels. The proposed LDPC code does not exhibit the error floor phenomena, in the region of interest, even in the presence of imperfect cophasing and receiver unbalances, and outperforms standard convolutional code of lower code rate in the observed impairments. The effects of number of iterations in decoding algorithm and codeword length on BER performance are also investigated.
