METHOD FOR SELECTING AN ADAPTATIONAL TRANSMISSION RATE AT MULTI-RATE WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a method for selecting the transmission rate according to the channel environment in a communication system using a multi-speed transmission. ; To this end the present invention is then sent a data packet, repeatedly performs an operation of determining a transmission success or a transmission failure through the reception whether or not the response signal for the transmitted data packet, and accumulates the transmitted number of successes or failures, according to the comparison result of the accumulated number of successful and success is set in advance the number of times the threshold value, or the accumulated number of failures and the failure count threshold value set in advance, providing a transfer rate selection methods optimize the transfer rate to the rising or falling channel environment that do. ; Through this, the present invention is it is possible to perform efficient channel adaptation according to the channel environment in a wireless communication system, there is an effect that can achieve high throughput. ; Transfer speed adaptive multi-rate transmission, 802.11, FTRA, CARA, QA, EA, ARF, Link Adaptation
