In this paper, we present a novel covert communication technique based on adaptive quantization index modulation (AQIM) and channel coding via the comparison of several existing ones.

比较目前几种信息隐藏技术，提出了一种基于自适应量化索引调制(AQIM)与信道编码实现信息隐藏通信的新方法。

The model supports the multi-rate non-ideal channel using adaptive modulation and coding (AMC), which is the key feature in the wireless networks to increase the effective transmission rate.

该模型支持采用自适应调制和编码(AMC)的多速率非理想信道，而AMC在无线网络中是增加有效传输率的关键技术。

The system also supports two level hierarchical channel coding and modulation, including uniform and multiresolution constellation.

系统还支持两层次式通道编码与调变，包括均匀与多分辨率群集。
