为明确光载波无线传输系统中, 复合传输相比单独传输的优越性, 实验对比了单独传能、单独通信、复合传输三种结构在传输距离为0.1 m、接收的光功率估值为3.5 mW、光通信速率为1 kbps时的输出特性.结果表明, 单独传能系统在与电感串联的负载为4 kΩ时, 电池板输出最大功率为1.82 mW, 复合传输系统在与电感串联的负载为5 kΩ时, 电池板输出最大功率为2.1 mW, 比单独 传能系统高出15%; 与电容串联的负载较低时复合传输系统输出信号波形发生畸变, 优化负载后波形得以改善, 相同条件下幅值比单独通信系统高出1.52 V.

In order to clarify the superiority of hybrid transmission performance in optical wireless transmission system, output characteristics of single energy transmission, single communication, and hybrid transmission were investigated in 0.1 m transmission link with received optical power of 3.5 mW and date rate of laser source of 1 kbps. When the single energy transmission system has a load of 4 kΩ in series with inductance, the maximum output power of the panel is 1.82 mW, when the hybrid transmission system has a load of 5 kΩ in series with inductance, the maximum output power of the panel is 1.82 mW, which is 15% higher than the former. The output signal waveform of the hybrid transmission system is distorted at a low load in series with capacitance. Optimized load can improve the performance of waveform. The amplitude in hybrid transmission system is higher than that of the single transmission system at 1.52 V in same conditions.
