摘要: 反向散射技术在物流领域得到广泛应用,不停车收费系统( ETC, electronic toll collection)是该技术的成 功商用案例。近些年来,随着物联网的兴起和大规模的商用,学术界和工业界提出多种新型的反向散射通信技术。 简要回顾了物联网和反向散射技术的历史,总结了新兴的反向散射通信技术,预测了其在物联网中的潜在应用, 并分析了其面临的关键问题,包括无线能量采集、接收方信号检测、多址接入、容量界和安全等。

Abstract: The origin of backscatter technology has been widely applied in logistics domain. One of the successful commercial applications of backscatter technology is electronic toll collection (ETC). Recently, with the extensive usage of Internet of Things (IoT), both academic world and industrial world proposes several new types of backscatter technologies for communications. The history of both IoT and backscatter was reviewed, the rising communication technologies of backscatter was concluded, their potential applications were predicted, and the coming challenges were analyzed, such as wireless energy harvesting, signal detection, multiple access, capacity bounds and security.
