Surat ini mengkaji prestasi kadar ralat bit asimptotik (BER) sistem komunikasi multihop dengan penyampaian amplify-and-forward ke atas Nakagami-m saluran pudar. Memandangkan sukar untuk mencari fungsi ketumpatan kebarangkalian (PDF) yang tepat bagi nisbah isyarat-ke-bunyi (SNR) keluaran di destinasi, kami menggunakan siri pengembangan PDF ini dalam kejiranan sifar. Berdasarkan hasil ini, ungkapan bentuk tertutup untuk purata BER dalam rantau SNR tinggi diperolehi. Keputusan berangka menunjukkan bahawa ungkapan BER asimptotik terbitan adalah tepat pada SNR sederhana dan tinggi untuk kedua-dua saluran taburan identik bebas (iid) dan saluran taburan bebas tidak seiras (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.
