Research and Development on Ultra High-speed Radio Access System - Fundamental Transmission Characteristic in ROF based Virtual Cellular Zone Communication System

摘要

In the ultra high-speed radio access system on microwave and millimeter wave band, radio-on-fiber based virtual cellular zone (ROF-VCZ) communication system is a system that can expand cellular zone where users can use common frequency bands. However, when the length of optical fiber extends, transmission delay between uplink and downlink also lengthens. We therefore need an access protocol that is robust against the delay and realizes ultra high-speed radio transmission. In this paper, we propose to use packet reservation dynamic time-slotted multiple access (PR-DSMA) protocol for ROF-VCZ communication system and evaluate its transmission performance such as throughput by computer simulation.
