管道内通信在结构健康监测、油气勘探、遥感等领域有着广泛的应用。管道基础设施的广泛部署为实现恶劣环境下的无线通信，特别是水下或地下通信提供了一种新的介质。高频（80khz以上）应力波在短范围内的混响使压电换能器能够传输信息。本文研究了应力波的传播、混响应力波通道特性以及几种可能的混响应力波通道技术。基于实验和仿真结果，单输入多输出正交频分复用（SIMO-OFDM）和上行单载波FDMA分别被认为是最适合于点对点和多用户场景下混响应力波通信的方案。评估结果表明，1×3 SIMO的频谱效率上限为3.18 bit/s/Hz，上行链路SC-FDMA的速率和容量为75.18 kb/s，总带宽为30 kHz。
In-pipe communication exists in broad applications such as structural health monitoring, gas and oil exploration, and remote sensing. The widely deployed pipeline infrastructure provides a new medium to realize wireless communications in the harsh environment, especially underwater or underground communications. The high frequency (above 80 kHz) reverberating stress wave in a short range allows piezoelectric transducers to transmit information. This paper investigates stress wave propagation, the reverberating stress wave channel characteristics, and several potential techniques for the reverberating stress wave channel. Based on our experimental and simulation results, single-input-multiple-output orthogonal frequency-division multiplexting (SIMO-OFDM) and uplink single-carrier FDMA are considered the most suitable schemes for reverberating stress wave communications in point-to-point and multi-user scenarios, respectively. Our evaluation results show the spectral efficiency upper bound is 3.18 bit/s/Hz for 1×3 SIMO and the rate-sum capacity for uplink SC-FDMA is 75.18 kb/s with 30 kHz total bandwidth.
