论文摘要
本文研究了非正交多访问(NOMA)辅助综合传感和通信(ISAC)网络。与传统的ISAC网络相比,将总带宽用于雷达检测和无线通信,建议的半ISAC网络允许将一部分带宽用于ISAC,其余的带宽仅用于无线通信。我们首先得出通信信号中断概率的分析表达式,包括雷达目标和通信发射器的信号。此外,我们得出了雷达回波的厄贡雷达估计信息率(REIR)的分析表达式。模拟结果表明,1)Noma ISAC的频谱效率比常规ISAC更好; 2)当我们扩大脉冲的密度时,会增强灵气。
This paper investigates non-orthogonal multiple access (NOMA) assisted integrated sensing and communication (ISaC) networks. Compared to the conventional ISaC networks, where the total bandwidth is used for both the radar detection and wireless communications, the proposed Semi-ISaC networks allow that a portion of bandwidth is used for ISaC and the rest of the bandwidth is only utilized for wireless communications. We first derive the analytical expressions of the outage probability for the communication signals, including the signals for the radar target and the communication transmitter. Additionally, we derive the analytical expressions of the ergodic radar estimation information rate (REIR) for the radar echoes. The simulation results show that 1) NOMA ISaC has better spectrum efficiency than the conventional ISaC; and 2) The REIR is enhanced when we enlarge the density of pulses.
