摘要
密集阅读器环境下的同信道干扰将显著降低阅读器识别性能,基于Nakagami-m多径信道模型和最大比合并(MRC)算法,推导了多天线分集RFID系统反向识别距离的数学期望值闭合表达式,并遵循ISO18000-6C标准的空口参数进行数值仿真,验证了推导的结论。
In the circumstance of dense readers,the identification performance of UHF RFID system is degraded by co-channel interference. The closed-form expression of mathematical expectation for reverse identification range of multi-antenna di-versity RFID system is deduced by means of Nakagami-m multi-channel model and maximal ratio combing（MRC）algorithm. Ac-cording to air interface parameters abiding by ISO18000-6C,the numerical simulation was carried out to prove the correctness of the deduction.
