提出了一种基于plotkin的极编码正交频分复用（P-PC-OFDM）方案，并对该方案在加性高斯白噪声（AWGN）、频率选择性瑞利（Rayleigh）、rici和Nakagami-m衰落信道上的误码率（BER）性能进行了评价。所考虑的Plotkin结构在结构上具有平行分裂，这促使我们将所提出的P-PC-OFDM方案扩展到编码合作场景。由于中继的有效协同一直是协作通信设计的关键，因此在中继节点上灌输了一种有效的信息位选择准则。为了评估所提出的合作方案的误码率性能，我们还在OFDM的背景下对传统的极编码合作方案进行了升级，作为适当的基准标记。蒙特卡罗模拟结果表明。本文提出的基于plotkin的极编码合作OFDM方案在AWGN信道上的性能比传统的极编码合作OFDM方案高0.5 ~ 0.6 db。由于在中继和目的节点分别采用了比特选择标准和联合连续取消解码，这种显著的误码率性能增益成为可能。此外，在相同条件下，所提出的编码合作方案比相应的非合作方案增益1 dB。
A Plotkin-based polar-coded orthogonal frequency division multiplexing (P-PC-OFDM) scheme is proposed and its bit error rate (BER) performance over additive white gaussian noise (AWGN), frequency selective Rayleigh, Rician and Nakagami-m fading channels has been evaluated. The considered Plotkin’s construction possesses a parallel split in its structure, which motivated us to extend the proposed P-PC-OFDM scheme in a coded cooperative scenario. As the relay’s effective collaboration has always been pivotal in the design of cooperative communication therefore, an efficient selection criterion for choosing the information bits has been inculcated at the relay node. To assess the BER performance of the proposed cooperative scheme, we have also upgraded conventional polar-coded cooperative scheme in the context of OFDM as an appropriate bench marker. The Monte Carlo simulated results revealed that the.proposed Plotkin-based polar-coded cooperative OFDM scheme convincingly outperforms the conventional polar-coded cooperative OFDM scheme by 0.5 ~ 0.6 dBs over AWGN channel. This prominent gain in BER performance is made possible due to the bit-selection criteria and the joint successive cancellation decoding adopted at the relay and the destination nodes, respectively. Furthermore, the proposed coded cooperative schemes outperform their corresponding non-cooperative schemes by a gain of 1 dB under an identical condition.
