Dalam makalah ini, kami menganalisis kesan ralat anggaran saluran dalam rangkaian penyampai dua hala (TWRN) berasaskan penguatan dan ke hadapan (AF) di mana modulasi penyesuaian (AM) digunakan dalam laluan penyampaian individu. Khususnya, kemerosotan prestasi yang disebabkan oleh ralat anggaran saluran disiasat ke atas Nakagami-m saluran pudar. Kami mula-mula memperoleh nisbah isyarat-ke-bunyi hujung ke hujung (SNR), fungsi pengedaran terkumpul dan fungsi ketumpatan kebarangkalian dengan adanya ralat anggaran saluran untuk TWRN berasaskan AF dengan modulasi penyesuaian (TWRN-AM) . Dengan menggunakan statistik SNR yang diperolehi, kami mempersembahkan ungkapan yang tepat bagi kecekapan spektrum purata dan kadar ralat bit dengan kekangan gangguan di mana penghantaran tidak berlaku semasa peristiwa terputus komunikasi dua arah. Berdasarkan hasil analisis kami yang diperoleh, skim peruntukan kuasa optimum untuk TWRN-AM dicadangkan untuk meningkatkan kecekapan spektrum purata dengan meminimumkan gangguan sistem.

Abstract: In this paper, we analyze the impact of channel estimation errors in an amplify-and-forward (AF)-based two-way relaying network (TWRN) where adaptive modulation (AM) is employed in individual relaying path. In particular, the performance degradation caused by channel estimation error is investigated over Nakagami-m fading channels. We first derive an end-to-end signal-to-noise ratio (SNR), a cumulative distribution function, and a probability density function in the presence of channel estimation error for the AF-based TWRN with adaptive modulation (TWRN-AM). By utilizing the derived SNR statistics, we present accurate expressions of the average spectral efficiency and bit error rates with an outage-constraint in which transmission does not take place during outage events of bidirectional communications. Based on our derived analytical results, an optimal power allocation scheme for TWRN-AM is proposed to improve the average spectral efficiency by minimizing system outages.
