超宽带分组无线Ad Hoc网络性能分析
Performance Analysis of Ultra-Wide-Band Ad Hoc wireless packet networks
摘要
超宽带技术被看作当前无线通信技术中最有前途的技术.本文根据UWB通信的多址方式,提出一种室内短距离分组移动自组网(ad hoc)的模型,然后讨论了UWB信号物理层与窄带信号不同的同步捕获问题和多址干扰问题,利用马尔可夫链分析了这种应用于UWB Ad Hoc无线局域网的时隙ALOHA-CDMA随机接入协议.结果表明,UWB的脉冲重复周期(To)与脉冲宽度(Tp)之比对性能的影响很大,只要设计合理,UWB信号在移动自组网就中可以充分发挥其优势,突破频谱瓶颈.
