本文开发了一种用于在上行链路两层以用户为中心部署的异构网络（HetNet）中的设备到设备（D2 D）通信的空间频谱感测（SSS）的建模和分析的新框架，其中小小区基站（SBS）被部署在具有由3GPP引入的称为热点的高用户密度的地方。研究了典型D2 D发射机（D2 D-Tx）在SSS期间上行链路用户的平均发射功率、空间虚警概率和空间漏检概率。在此基础上，进一步分析了典型D2 D用户的覆盖概率和D2 D网络的区域频谱效率（ASE）。仿真结果验证了我们的分析，并展示了基于SSS的D2 D通信在未来无线网络中的优势。
This paper develops a novel framework for the modeling and analysis of spatial spectrum sensing (SSS) for device-to-device (D2D) communications in uplink two- tier user-centric deployed heterogeneous networks (HetNets), where small cell base stations (SBSs) are deployed in the places with high user density termed hotspots introduced by 3GPP. We study the average transmit power of uplink users, the probability of spatial false alarm and the probability of spatial miss detection of a typical D2D transmitter (D2D-Tx) during SSS. Based on the results, we further characterize the coverage probability of a typical D2D user and the area spectral efficiency (ASE) of D2D networks. Simulation results verify our analysis and demonstrate the advantages of SSS-based D2D communications in future wireless networks.
