首发时间:2012-12-27
摘要:近年来,60GHz 毫米波通信凭借其数GHz的免许可连续带宽和支持Gbps传输速率的能力,受到了广泛的关注。其支持的应用主要为高清视频的无损传输、千兆以太网等,此类通信场景往往需要支持多条高速链路在同一空间共存,对系统的干扰抑制和空间重用能力提出了很高的要求。同时,60GHz通信特有的定向传输和易阻隔特性,也蕴含着巨大的空间重用潜力。本文对在60GHz通信网络中,利用反射体作为虚中继进行干扰抑制和空间重用的机制作了研究,创建了一种基于虚中继的自适应的STDMA机制。仿真结果表明,该方案可以有效的提高网络的整体性能,起到干扰抑制和空间重用的作用。

A virtual relay based adaptive STDMA scheme in 60 GHz communication network
Abstract:In recent years, 60 GHz millimeter-wave (mm Wave) communication has been attracting much attention due to its large available GHz bandwidth and Gbps transmission capability. It enables numerous wireless applications such as uncompressed transmission of high definition TV (HDTV) and wireless gigabit Ethernet. Most of these applications acquire several high-rate links working at the same time in a short range, which calls for high demands in the ability for interface mitigation and spatial reuse. Meanwhile, 60 GHz has very high spatial reuse ability due to its feature of directional transmission and blockage problem. This paper investigates virtual relay based interface mitigation and spatial reuse scheme in 60GHz wireless communication network, proposes an adaptive virtual relay based STDMA scheme.The simulation results show that network performance of 60 GHz communication network can be improved effectively by using virtual relay based interface mitigation and spatial reuse scheme.
