This paper proposes an impulse radio ultrawideband (IR-UWB) wireless network channel model for next-generation wireless avionic system (NGWAS). Complexities such as poor network localization, redundant wiring, network security flaws, suitable physical proximity to the aircraft system's controller and need to guarantee scalable wireless network access have necessitated the adoption of wing system units of a passenger aircraft for this scheme's deployment. The proposed IR-UWB approach aims at alleviating the attendant drawbacks by selecting optimal channel path from available paths on the basis of bit error rate (BER), based on the numerical results obtained from the Saleh–Valenzuela (S-V) principle. Cooperative relay transmission schemes factored upon transmission power, overall outage probability and spectral-energy efficiency tradeoffs for the relay network communication were also investigated and compared with the noncooperative schemes. Simulation results validate maximum data packet delivery while a strong network signal strength is attained. Comparative approach of the performances of the IR-UWB standardized channel models are also evaluated.

下一代无线航空电子系统的超宽带网络信道模型

本文提出了一种用于下一代无线航空电子系统（NGWAS）的脉冲无线电超宽带（IR-UWB）无线网络信道模型。复杂的网络定位、冗余布线、网络安全缺陷、与飞机系统控制器的物理距离合适以及需要保证可扩展的无线网络访问等复杂性，使得该方案的部署需要采用客机的机翼系统单元。提出的 IR-UWB 方法旨在通过根据从 Saleh-Valenzuela (SV) 原理获得的数值结果，基于误码率 (BER) 从可用路径中选择最佳信道路径来减轻伴随的缺点。基于传输功率的协作中继传输方案，还研究了中继网络通信的总体中断概率和频谱能量效率权衡，并与非合作方案进行了比较。仿真结果验证了最大的数据包传输，同时获得了强大的网络信号强度。还评估了 IR-UWB 标准化信道模型性能的比较方法。
