摘要:

介绍了一种工作在60 GHz的混合无线千兆以太网室内通信系统的设计与实现。由于60 GHz无线电链路仅在单个房间配置中运行,因此使用额外的光纤无线电(RoF)链路来确保住宅环境的所有房间内的通信。该系统采用低复杂度的基带处理模块。字节同步技术被设计为提供高值的前导检测概率和非常小的值的错误检测概率。传统的RS(255,239)编码器和解码器用于信道前向纠错(FEC)。FEC参数由较高编码增益和硬件复杂度之间的权衡来确定。在875 Mbps的比特出错率测量的结果,提出了各种天线配置。

英文摘要:

This paper presents the design and the realization of a hybrid wireless Gigabit Ethernet indoor communications system operating at 60 GHz. As the 60 GHz radio link operates only in a single-room configuration, an additional Radio over Fiber (RoF) link is used to ensure the communications within all the rooms of a residential environment. The system uses low complexity baseband processing modules. A byte synchronization technique is designed to provide a high value of the preamble detection probability and a very small value of the false detection probability. Conventional RS (255, 239) encoder and decoder are used for channel forward error correction (FEC). The FEC parameters are determined by the tradeoff between higher coding gain and hardware complexity. The results of bit error rate measurements at 875 Mbps are presented for various antennas configurations.
