Esta carta estuda o desempenho da taxa de erro de bit assintótica (BER) de sistemas de comunicação multihop com retransmissão amplificada e encaminhada sobre Nakagami-m canais desbotados. Como é difícil encontrar a função de densidade de probabilidade (PDF) exata da relação sinal-ruído (SNR) de saída no destino, recorremos à expansão em série desta PDF na vizinhança de zero. Com base neste resultado, é derivada uma expressão de forma fechada para o BER médio na região de alto SNR. Os resultados numéricos mostram que a expressão assintótica derivada de BER é precisa em SNR médio e alto para canais independentes distribuídos de forma idêntica (iid) e independentes não distribuídos de forma idêntica (inid).

Abstract: This letter studies the asymptotic bit error rate (BER) performance of multihop communication systems with amplify-and-forward relaying over Nakagami-m fading channels. Since it is difficult to find the exact probability density function (PDF) of the output signal-to-noise ratio (SNR) at the destination, we resort to the series expansion of this PDF in the neighborhood of zero. Building upon this result, a closed-form expression for the average BER in the high SNR region is derived. Numeric results show that the derived asymptotic BER expression is accurate at medium and high SNR for both independent identically distributed (i.i.d.) and independent non-identically distributed (i.n.i.d.) channels.
