Labeling diversity (LD) is a well-known technique proposed for multi-antenna Wireless local area network (WLAN) applications . In this paper, we propose LD for three-terminal cooperative communication schemes i.e., Decode and Forward (DF) and Coded-cooperative (CC) schemes with each terminal using a single antenna for transmission. The Boosted space-time codeword is jointly constructed by source and a relay node in two phases and joint iterative detection and decoding are used at the destination node. This technique shows that the gains from LD can be further enhanced when used in cooperative communication schemes. Numerical analysis reveal that the proposed schemes DF and CC provide full diversity gains, over non-cooperative schemes, later scheme being the most successful one, under identical conditions using less number of antennas at each communication node and with reduced receiver complexity.

标记分集（LD）是为多天线无线局域网（WLAN）应用程序提出的一项众所周知的技术。在本文中，我们为三端协作通信方案（即解码转发（DF）和编码协作）提出了LD。（CC）方案，每个终端使用单个天线进行传输。Boosted时空码字是由源节点和中继节点分两阶段共同构建的，目标节点使用联合迭代检测和解码。该技术表明，在协作通信方案中使用时，可以进一步提高LD的增益。数值分析表明，与非合作方案相比，提出的方案DF和CC可提供全部分集增益，后一种方案是最成功的方案，在相同条件下，每个通信节点的天线数量较少，接收机复杂度降低。
