Implementation of an adaptive channel coding strategy in shortwave communication Lin Yi-qing, CUI Hui-jun, TANG Kun (Department of Electronic Engineering, Tsinghua University, Beijing, 100084, China) Abstract: This paper proposes an adaptive channel coding strategy, which chooses different FEC code dynamically according to feedback information of the current state of the channel, so that acquires both high efficiency as well as excellent error-correcting performance. This method has been implemented in shortwave communication, and gets good gains.
