摘要
在介绍正交额分复用(OFDM)技术和单载波频域均衡(SC-FDE)技术原理的基础上,分析了两种技术的特点。以克服多途干扰、实现水声通信的高速率传输为目的,研究了在现有水声信道模型中两种技术的可靠性、有效性及抗多径能力。仿真结果表明,它们均具有较强的抗多径干扰能力。正交额分复用和单载波频域均衡技术在现代高速水声通信中应具有很好的发展前景。
The principle of OFDM multi-carrier system and single carrier frequency domain equalization（ SC- FDE） are firstly introduced. Their characteristics are analysed. In order to overcome many cochannel interference and carry out transmission of UWA communication＇ s high-speed velocities over UWA channels, their reliabilities and validities and capability resisting multi-pathway interference are studied at UWA channel model. The results of simulation proved their capabilities overcome cochannel interference. The OFDM and SC-FDE will possess the bet- ter development in the UWA communication.
