摘要 在宽带通信环境中提出一种多中继协同的差分传输方法.该方法采用差分酉调制、放大转发(AF)及最大比合并技术,以可解耦的方式在空间域和频率域上获得了完全的协同分集和频率分集增益.相对于差分协同空频分组编码,降低了编解码复杂度,便于调整系统获得的分集增益,而且在中继个数和分组长度相同的情况下还能获得更高的协同分集和频率分集增益.仿真实验结果与理论分析具有很好的吻合性. A differential transmit scheme based on multiple-relay cooperating is proposed in broadband communication environment. By exploiting several technologies including differential unitary modulation, amplify-and-forward and maximum ratio combining, the scheme can acquire full spatial and frequency diversity gains in the manner of decoupling. Compared to the differential space-frequency block codes, the proposed scheme not only reduces coding and decoding complexity but also easyly adjusts diversity gain. In addition, it can acquire higher spatial and frequency diversity gains with the same relay node numbers and block length. Simulation consists with theoretical analysis.
