The Complexα-μFading Channel with OFDM Application

Abstract: The aims of this paper are threefold: (i) to present a model for the complex -fading channel; (ii) to propose an efficient, simple, and general method to generate complex -samples; (iii) to make use of this channel in order to assess the bit error rate performance of an OFDM system. An analytical framework is then used, whose output is validated through Monte Carlo simulation. Several important conclusions concerning the system performance as a function of the channel parameters, namely, nonlinearity, clusteri… Show more

“…The actual cause of considering the SR fading channel is to evaluate the effect of shadowing on the secrecy performance in satellite communication. Then the best relay is chosen among the given N relays and the data is sent from this best relay to the users B through best relay‐user, NP link which is designed as the αμ fading channel because this simple yet flexible model can be used to operate in different environmental conditions as required in 5G communications [50]. The eavesdroppers E are wiretapping the transmitted data via NQ link.…”

“…i) ∆ω = 0 (os processos W 1 e W 2 propagando-se com frequências ligeiramente diferentes, ou seja ω 1 = ω 2 ) e T > 0 (banda de coerência finita) ou ii) ∆ω = 0 e T = 0 (canal plano, ou de maneira semelhante, banda de coerência infinita). Portanto, é razoável, e necessário, admitir correlação cruzada fase-quadratura e quadratura fase dos processos W 1 e W 2 descritos em (1). A mesma argumentação aplica-se ao coeficiente λ 1 pois λ 2 = ∆ωT λ 1 .…”

“…Admitindo-se o desbalanceamento de potência entre as componentes em fase e em quadratura, um modelo de fase foi apresentado para Nakagami-m em [6], em que apenas para a condição m = 1 (Rayleigh) a fase é uniforme. Outros modelos de fase surgiram para as distribuições α-µ [1], η-µ [3] e κ-µ [2], sendo que em seguida foram validados em situações práticas [7], [8]. O modelo de fase proposto [6] foi utilizado em diversos estudos de desempenho de sistemas OFDM [1] e capacidade de canais MIMO [9].…”

“…Tal fato se dá uma vez que quanto maior for valor de , mais determinístico será o canal e, portanto, menos suscetível a variações. Já se o valor de for pequeno, implica em uma severa não linearidade do meio, i.e., uma péssima condição do canal (FREITAS et al, 2017;LEI et al, 2017).…”
