摘要
本文面向无线移动信道的高速率业务展开了对自适应信道的各种调制技术的讨论，初步提出了一种基于QAM及其各种变形的带宽有效调制方案，找到了一条在BPS与BER性能上都有较佳表现的调制途径。
This paper, targeting the wireless channel with high speed transmission rate, presents discussions on the modulation technology for adaptive channel. An initial scheme based on QAM and all its varied effective bandwidth modulations is proposed, thus finding a modulation approach with better performances between BPS and BER.
