摘要
由于自适应编码调制技术在宽带无线网络中对于改善频谱利用率和增加数据速率来说是一项能力很强的技术,因此本文针对刚提出的CT-TCM技术,将其与RCPT和ARQ技术结合起来,讨论了一种新的自适应编码调制方案。并对实现该方案的一些具体细节进行了详细的阐述。
Adaptive coded modulation is a powerful technique for improving the energy efficiency and increasing the data rate in the wide wireless network. This paper, therefore, combines the recently proposed technique of CT-TCM with RCPT and ARQ, on the basis of which, it discusses a new schedule of adaptive coded modulation with some details in realizing this schedule covered.
