摘要

只提供摘要形式。介绍了日本横须贺无线电通信研究中心研制的毫米波无线接入系统。首先讨论日本的60ghz标准。综述了几种应用，并详细介绍了一种可传输多个视频通道的室内应用。针对室内和室外毫米波系统，提出了一种能够降低60 GHz硬件成本的外差传输技术。从相位噪声的角度给出了外差传输技术的实验结果。提出了短程型自组织系统。我们的想法已经在IEEE 802.15 TG3a中提出，作为一个可选的物理层。介绍了该方案。固定无线接入(FWA)系统利用毫米波频率的优势。讨论了由CRL开发的下一代FWA系统，并提出了FWA系统的新频段。CRL目前正在横须贺市区使用32 GHz、38 GHz和60 GHz频段制作FWA测试平台。进一步介绍了试验台的结构，并讨论了FWA的应用。

Research trend of millimeter-wave systems and technologies at Communication Research Laboratory

Summary form only given. A novel millimeter-wave wireless access system developed by CRL Yokosuka Radio Communication Research Center is presented. First we discuss the Japanese 60 GHz standardization. Several applications are reviewed and one indoor application which can transmit a number of video channels is presented in detail. Heterodyne transmission techniques, which can reduce the cost of 60 GHz hardware, are proposed for indoor and outdoor millimeter-wave systems. Experimental results of the heterodyne transmission techniques are presented in terms of phase noise. Short-range type ad-hoc systems are proposed. Our idea has been proposed to IEEE 802.15 TG3a as an alternative PHY layer. The proposal is described. Fixed wireless access (FWA) systems utilize the advantages of millimeter-wave frequencies. The next-generation FWA system developed by CRL is discussed and new-frequency bands for FWA systems are proposed. CRL is now making a FWA testbed in the Yokosuka city area using 32 GHz, 38 GHz and 60 GHz bands. The configuration of the testbed is further presented and applications of FWA are discussed.
