An Efficient Transmission Scheme Using Simultaneous Transmit and Receive Technology for Railroad Communications in Next Generation Wireless LAN

Abstract

In next generation Wireless Local Area Network (WLAN), increasing spectral efficiency is indispensable in order to provide enhanced throughput. Spectral efficiency can be increased though Simultaneous Transmit and Receive (STR) technology. In this paper, an efficient WLAN transmission scheme using STR technology is proposed. Since STR technology allows simultaneous reception while receiving, at most network throughput can be doubled. However, in order to utilize STR technology, at least two non- interfering parties are required. Railroad communication environment of busy railroad station is able to provide good STR environment with plenty number of non-interfering communication parties. Therefore, the proposed scheme is able to provide very efficient railroad communication scheme.
