[Paper] High Efficiency Retransmission Control for Bidirectional Field Pick-up Unit Systems

Abstract

In this paper, we propose a novel packet transmission scheme to improve retransmission efficiency in a bidirectional field pick-up unit (FPU). The proposed scheme's effects on throughput and average delay time are confirmed through the evaluation of computer simulations.FPU systems, such as television (TV) rebroadcast systems, transmit recorded movies or live footage from terminals to satellite stations by remote broadcast. Because high-definition broadcasting requires reliable transmission systems to carry high-resolution images and sound quality, the development of a bidirectional FPU with a packet exchanging process has become critical in recent years.To improve transmission efficiency, we propose a packet-based bidirectional transmission system that uses both an efficient retransmission control scheme and a burst transmission scheme. Computer simulation results demonstrate that throughput of the proposed scheme is up to approximately five times greater than that of a conventional FPU, while its transmission average delay is approximately 80% less.
