Radio-frequency identification (RFID) communication system known as auto-id has experienced tremendous growth worldwide, considering a flexible mechanism for of objects. Degradation data transmission due to external interference and RFID itself (tags reader collision) is one the most important factors restrict development direct bearing on performance whole system. In order eliminate tag collision problem in an variety different anti-collision algorithms have been proposed by many researchers successful adoption massive scale. Synthesizing much algorithm conducting in-depth analysis, we propose new combined primary digital technique based time division (TD) gold code efficiently suppress tag-to-tag interference.
