UHF RFID系统相位噪声的研究与仿真
Study and Simulation of Phase Noise for UHF RFID System
摘要
Abstract
This paper introduces an analysis method of phase noise requirements on a local oscillator for a UHF Radio Frequency Identification (RFID) system. In general case, phase noise requirements are derived considering a reciprocal mixing with an interference signal. In UHF RFID system, the same oscillator is used for the transmitted signal and the Local Oscillator(LO), range correlation phenomenon effects the phase noise requirements. This paper derives new phase noise equation considering the range correlation effect on the RFID system and a simulation is done. Simulation results for UHF RFID system show that range correlation effect is the important factor in RFID system design.关键词
