摘要

我们提出了使用光无线通信(OWC)传输的心电图(ECG)信号的特性。该系统使用发光二极管(LED)和硅光电二极管作为光学无线天线。OWC系统采用视距(line-of-sight, LOS)配置，在50 cm ~ 1 m范围内传输光信号。传输后，对接收到的心电信号进行高斯滤波，并利用香农能量进行分析，得到信号峰值。评估了精度、灵敏度、检测错误率和阳性预测值，以确定使用OWC系统传输的信号是合格的。我们仔细表征了传输后的心电图信号，发现它们具有较高的准确性。通过对心率变异性的分析，提供了光无线传输后心电信号的心率状况。

Transmitting ECG waveforms by means of optical antennas

We present the characterization of electrocardiogram (ECG) signals transmitted using optical wireless communication (OWC). The system used a light-emitting-diode (LED) and silicon photodiode as optical wireless antennas. OWC system transmitted the optical signal within the distance of 50 cm to 1 m with line-of-sight (LOS) configuration. After the transmission, the received ECG signal was filtered using Gaussian filter and analyzed using Shannon energy to obtain signal peaks. Accuracy, sensitivity, detection error rate and positive predictive values were evaluated to qualify the signal that is transmitted using OWC system. We carefully characterize the electrocardiogram signals after transmission and found that they present high accuracy. Heart rate variability was analyzed to provide the heart rate condition from ECG signals after the optical wireless transmission.
