面向6G高铁移动场景的R10编码传输方案
R10 Coding-based Transmission Scheme for 6G High-speed Rail Mobile Scenarios
摘要
Abstract
In the era of 6G,an increasing number of intelligent applications are being deployed on high-speed trains,necessitating reliable and efficient transmission services from mobile rail networks.However,due to the high-speed movement,the vehicle-to-ground communication links exhibit rapidly changing characteristics,making traditional channel estimation and feedback mechanisms inadequate for effectively tracking these fast variations.Consequently,there is an urgent need for an efficient forward error correction scheme without feedback in high-speed rail mobile networks.Given the advantages of R10 coding,which integrates the benefits of fountain codes and systematic codes,it has been introduced into high-speed rail mobile scenarios.A novel vehicle-to-ground coding transmission scheme based on R10 coding is proposed.In this scheme,the encoding process at the transmitter involves adding structured redundant information combined with specific coding rules to generate and send an arbitrary number of encoded symbols,while the receiver only needs to collect a certain number of encoded symbols along with structured redundant information to more accurately reconstruct the original data,thereby achieving a lower bit error rate.Simulation experiments indicate that the proposed scheme significantly reduces the bit error rate compared to traditional feedback-free coding transmission schemes.For instance,using Turbo codes as a reference,the bit error rate is reduced by approximately 13％.关键词
