论文摘要
无线光学通信（WOC）具有多达数百个Terahertz的载体，该载体具有多种优势，例如Ultrawide带宽和无电磁干扰。传统的WOC使用光线发射器，例如发光二极管（LED），定向LED和激光面临衰减或跟踪方面的主要挑战。共振光束通信（RBCOM）满足低衰减，非机械移动性和多次访问的要求。然而，与常见的非回声通道相比，RBCOM通道经历了回波干扰。呈现基于光学滤波的干扰消除方法以及示例性的无干扰RBCOM系统。
Wireless optical communications (WOC) has carriers up to several hundred terahertz, which offers several advantages, such as ultrawide bandwidth and no electromagnetic interference. Conventional WOC that uses light transmitters such as light emitting diodes (LEDs), directed LEDs, and lasers are facing major challenges in attenuation or tracking. Resonant beam communications (RBCom) meets the requirements of low attenuation, non-mechanical mobility, and multiple access. Yet, RBCom channel undergoes echo interference in contrast to common non-echo channels. An interference elimination method based on optical filtering is presented along with an exemplary interference-free RBCom system.
