摘要:

本文研究了三路中继信道的频谱效率和能量效率。首先,针对不同的中继协议,推导了3路中继信道的可达和速率表达式。此外,提出了3路中继信道容量的外界。其次,利用推导出的可达和速率表达式,设计了用户端和中继端的联合功率分配算法,以最大化系统能量效率。数值结果证实,并提供洞察力的理论研究结果。

英文摘要:

Spectral and energy efficiency in 3-way relay channels are studied in this paper. First, achievable sum rate expressions for 3-way relay channels are derived for different relaying protocols. Moreover, an outer bound for the capacity of the 3-way relay channel is presented. Next, leveraging the derived achievable sum rate expressions, two algorithms for joint power allocation at the users and at the relay are designed so as to maximize the system energy efficiency. Numerical results are provided to corroborate and provide insight on the theoretical findings.
