为了构建灵活的水下无线传感器网络，本文讨论了一种具有同步功率传输的水下可见光通信系统。为了实现该系统，接收的光功率用于数据通信和功率传输，并且需要设计用于将信号分离为交流（AC）和直流（DC）的接收器。接收电路采用直流低通滤波器和交流高通滤波器相结合的结构。此外，我们还分析了所设计的AC/DC分离滤波器在太阳能电池板作为接收机时的误码性能和电源性能。作为一种调制方案，我们考虑反脉冲位置调制（IPPM），这将实现稳定的电源。结果表明，在误码性能方面，IPPM比OOK具有更高的性能。与PPM相比，IPPM的性能恶化了约4.78 dB，由于每比特的高发射功率。然而，高的每比特发射功率对于电源是重要的，并且PPM和IPPM在这些调制方案的相同脉冲幅度下表现出相似的BER性能。在CV性能方面，在200 kbps的比特率下，IPPM的CV比OOK提高了20%，比PPM提高了1.1%。根据这些结果，IPPM可以实现稳定的电力供应。
In this paper, for constructing flexible underwater wireless sensor network, we discussed an underwater visible light communication system with simultaneous power transfer. For realizing the system, the received optical power is used for both data communication and power transfer, and it is necessary to design the receiver for separating the signal to alternate current (AC) and direct current (DC). We employ the receiver circuit based on low pass filter for DC signal and high pass fileter for AC signal. Moreover, we analyzed the BER performance and power supply performance when the designed AC/DC separation filter is based solar panel is used as the receiver. As a modulation scheme, we consider inverse pulse position modulation (IPPM) which would achieve stable supply of power. As a result, in the BER performances, IPPM show the higher performances compared to OOK. Compared to PPM, the performances for IPPM deteriorated by about 4.78 dB due to the high transmitted power per bit. However, the high transmitted power per bit is important for power supply, and PPM and IPPM show similar BER performances when the same pulse amplitudes of these modulation schemes. In the CV performances, CV of IPPM is improved by 20% compared to OOK and 1.1% compared to PPM with the bit rate of 200 kbps. From these results, IPPM can achieve stable supply of power.
