Abstract (in Japanese) (See Japanese page) 
(in English) In this work, we study the level crossing rate (LCR) and the average fading duration (AFD) of the beating signal under concurrent transmission (CT). In multi-hop wireless sensor networks (WSN), CT is a technique that can greatly improve the network and MAC layer efficiency by allowing synchronized packet collisions. However, the beating effect resulted from the carrier frequency offsets (CFO) between the sensor nodes causes performance degradation of physical-layer reception. By analyzing the AFD, the performance degradation due to the beating effect can be characterized. We provide the mathematical derivation of LCR and AFD under the concurrent transmission scenario and verify it by Monte-Carlo method. We prove that a higher part-to-part carrier frequency deviations with more CT nodes results in shorter AFD as well as better the receiver performance.
