Pulse Harmonic Modulation (PHM) is a novel pulse-based (carrierless) modulation method for wideband, low power data transmission across inductive telemetry links that operate in the near-field domain. PHM utilizes two or more unidentical pulses during each bit period to minimize inter-symbol interference (ISI). In this paper, we describe the PHM concept and demonstrate its operation with a proof-of-concept prototype, which achieves a data rate of 5.2 Mbps at 1 cm coil separation with a bit error rate (BER) of 10(-6).
脉冲谐波调制（PHM）是一种新颖的基于脉冲（无载波）的调制方法，用于在近场域运行的感应遥测链路中进行宽带、低功耗数据传输。PHM在每个比特周期内使用两个或更多不同的脉冲，以最小化符号间干扰（ISI）。在本文中，我们描述了PHM概念，并通过一个概念验证原型展示了其操作，该原型在1厘米线圈间距下实现了5.2 Mbps的数据速率，误码率（BER）为10^(-6)。
