摘要
3提出了一种基于协作判决的极化选择译码转发方案。首先，根据瑞利衰落信道的信道状态信息（CSI），给出了一种码率随 CSI 变化的极化码构造方案。然后，对中继预选择后再选择译码转发。最后，将所提极化码用于该协作系统，利用其编译码复杂度低，抗干扰强等优势。仿真表明：在衰落信道下，所构造的极化码相比现有码率固定编码，在误码率为10<sup>−3</sup>时，约有0.3 dB增益。在多中继协作下，当误码率为10<sup>−3</sup>时，所提方案相对于现有DF Poalr+方案和极化编码协作（NPCC）方案，分别有约0.8 dB和1.3 dB的性能增益。
Abstract
An improved Polar selective decoding and forwarding (IPSDF) scheme based on cooperative threshold de-cision was proposed.Firstly
a new construction of Polar codes according to the fading channel state information (CSI) was proposed.Then
a relay with best CSI was selected from the candidate relay set as the best relay.In addition
the proposed Polar codes were introduced into the cooperative communication system
to get coding gain and reduce the complex of encoding and decoding.Simulation results show that the proposed Polar codes achieve about 0.3 dB gain at bit-error-rate (BER) of 10<sup>−3</sup>.And using a classic multi-relay cooperative model
the proposed scheme achieves about 0.8 dB and 1.3 dB gain at BER of 10<sup>−3</sup>
when compared with those the existing DF Polar+ and network Polar coded coopera-tion scheme.Therefore
the IPSDF scheme can be used to improve BER performance in a multi-relay cooperative system and it is quite suitable for heterogeneous network applications in cooperative communication.
