In a UHF passive RFID system, a reader transmits an unmodulated continuous wave (CW) to tags, which not only provides energy to tags but also serves as the carrier of tag backscatter signals.

在超高频被动式射频辨识系统里，读取器传送未调变过之连续波讯号给标签，其不但可提供能量给标签也作为标签反向散射讯号的载波。

Combining the advantages of various anti-collision methods, in this paper it proposes an IRCM based anti-collision protocol against the RFID system with multi-channels and dense reader environment.

结合现有多种抗冲突方法的优点，提出一种针对多信道的、阅读器密集分布的RFID系统的基于IRCM的抗冲突协议。
