Research on Channel Coding in Underwater Acoustic Communication Combined with OFDM Technology
, 2005 正交频分复用（OFDM）技术是一种多载波数字调制技术，它是一种实现高速无线数据通信的良好方法。在无线通信领域中，OFDM技术得到广泛的应用并成为第三代移动通信的主流技术。然而，将OFDM技术应用于水声通信中，在国内的研究尚处于起步阶段。水声信道是一个极其复杂的时间－频率－空间变化，强多径干扰，带宽有限且噪声干扰严重的信道，在这样的信道环境下实现通信系统的高速、可靠传输是极具挑战性的。OFDM系统中插入保护间隔后，若符号定时同步的起始时刻落在保护间隔内，则可以避免ISI并减小ICI，然而 ...

Efficient LLR Calculation for Non-Binary Modulations over Fading Channels
, 2010 Log-likelihood ratio (LLR) computation for non-binary modulations over fading channels is complicated. A measure of LLR accuracy on asymmetric binary channels is introduced to facilitate good LLR approximations for non-binary modulations.
