“…Differently from Bessate and El Bouanani, 16 we extend our study here to be also valid for independent but not necessarily identically distributed (i.n.i.d) WFC. The first one relied on the moment-based density approximants methods, by evaluating the 3 first moments of the Weibull RVs sums, while the second approach 13-15 approximates the cumulative distribution function (CDF) by a convolution expression, yielding the approximate PDF.…”

In this paper, we investigate the analytical performance of the multiple-input multiple-output system (MIMO) with orthogonal space-time block codes (STBCs) subject to Weibull fading channels (WFC). Space-time block code technique provides an efficient pattern for wireless transmission over various fading channels using multiple transmit antennas. Two approximating methods of the sum of independent Weibull random variables are studied. For each approach, we derive accurate approximate expressions for several performance metrics of MIMO-STBC system operating under independent and nonidentical WFC. The proposed approximations are expressed in terms of 2 generalized hypergeometric functions, namely, Fox's H and Meijer's G functions. All the derived approximate expressions prove high accuracy, while compared with the simulation results established via Monte Carlo method and Kolmogorov-Smirnov test as well.Although the 2 approaches have approximately the same accuracy, the second method approximate expressions are much less complex than those of the first method. KEYWORDS channel capacity, Fox's H function, Meijer's G function, MIMO-STBC, probability density function (PDF), symbol error rate, outage probability, Weibull fading channels (WFC) | INTRODUCTIONTo overcome the problem of transmit diversity technique for the multiple-input multiple-output (MIMO) systems, several interesting coding and modulation techniques have been attacked in various ways recently. One famous modulation scheme is the orthogonal space-time block codes (STBCs). 1 A generalization of STBC has been investigated later in Tarokh et al. 2 Based on several studies, it is proven that the STBC can ensure the same diversity order as maximal-ratio combining (MRC). On the other hand, the monopath channel capacity is known to be less than the one of MIMO system. 3 The main advantage of STBCs is that the maximum probability decoding can be reached using a linear processing at the receiver. 4 Shin and Lee 5 analyzed, using the moment-generating function-based approach, the exact average symbol error rate (ASER) of MIMO-STBC system with some modulation schemes under Nakagami-m fading channels. In Pérez et al, 6 accurate approximate outage capacities of MIMO-STBC over several kinds of fading distribution such as Rayleigh, Rice, Nakagami-m, and Weibull were derived. The channel capacities under adaptive transmission policy of MIMO-STBC operating under Rayleigh fading channels were derived in closed form in Maaref and Aissa. 7 In addition to the small-scale fading, the shadowing, ie, large-scale fading, can affect the signal during its propagation, which will extremely reduce the advantages of MIMO system. In Yang, 8 the shadowing was modeled via the lognormal

“…In [15] , the PDF of a MIMO-system was estimated using a Finite Mixture with Expectation-Maximization (FM-EM) approach over i.i.d WFC. By the use of two new approximation PDFs of the Weibull's sum RVs [16]- [17], we investigated the MIMO-STBC performance over independent and not necessarily identically distributed (i.n.i.d) Weibull fading channels (WFC). [18] has been used to create a tight approximation sum's PDF of altogether correlated and uncorrelated Weibull RVs.…”

MIMO systems have shown to be effective in addressing today’s high demand for WC, particularly next generation (4G and 5G) mobile technologies, by combating the problem of fading and improving the quality and rate of wireless communications. MIMO-systems with space-time block codes (STBC) is a good choice to provide a complete variety with coherent flat-fading channels. We used a new accurate approximation probability density function (PDF) of the totality of correlated Weibull random variables to examine the performance metrics of MIMO-STBC systems with correlated Weibull fading channels and to emphasize the correlation impacts on such systems in this work. New tight approximation equations for numerous performance metrics, like OP, average capacity under various rate adaption methods, and average symbol/bit error rate (ASER/ABER), have been derived based on this PDF. The Monte-Carlo simulation method has validated all derived expressions.
