Abstract

Orthogonal frequency division multiplexing (OFDM) communications in the presence of motion is investigated using data collected from the Kauai Acomms MURI 2008 (KAM08) experiment, conducted off the western side of Kauai, Hawaii, in June-July 2008. The experiment involved a vertical array moored in 106 m deep shallow water and a source towed at a speed of 3 knots at ranges between 600 m and 6 km. In order to attain reliable communications with only a single receive element, a synthetic aperture approach is applied. After combining multiple transmissions, an error-free reception is achieved with a low-density parity-check code, confirming the feasibility of coherent synthetic aperture communications using OFDM.

摘要

正交频分复用（OFDM）通信在存在运动的情况下进行了研究，使用了 2008 年在夏威夷考艾岛西部进行的 Kauai Acomms MURI 2008（KAM08）实验中收集的数据。该实验涉及一个系泊在 106 米深的浅水中的垂直阵列和一个以 3 节的速度拖曳的源，范围在 600 米到 6 公里之间。为了仅使用单个接收元件实现可靠的通信，应用了合成孔径方法。在组合多次传输后，使用低密度奇偶校验码实现了无差错接收，证实了使用 OFDM 的相干合成孔径通信的可行性。
