Research on Channel Coding in Underwater Acoustic Communication Combined with OFDM Technology
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 ...

箝位电路损耗计算是IGCT-MMC换流阀电气设计、运行损耗评估,以及阀冷却系统设计的基础。在分析IGCT-MMC子模块箝位电路工作原理的基础上,基于IGCT关断电流及二极管反向恢复电流的指数函数模型,建立了子模块换流暂态过程箝位电路的等效模型,提出了子模块箝位电路损耗的解析计算方法。对比试验测量和理论计算结果,验证了所提出损耗计算方法的有效性。
