Performance Evaluation of Q-Algorithm with Tag Number Estimation Scheme

Performance of Channel Estimation Algorithm with Joint Channel Estimation Scheme

In this paper, multi-cell channel estimation algorithm based on successive interference cancellation (SIC).This channel algorithm is also used for Time Division Synchronization Code Division Multiple Access Systems (TD-SCDMA). TD-SCDMA is the country's standard of 3G mobile telecommunication. This reduces the number of users in each timeslot, which reduces the implementation complexity of multi...

Initial Slot-Count Selection Scheme with Tag Number Estimation in Gen-2 RFID System

Improved Efficient RFID Tag Estimation Scheme

DFSA (Dynamic Frame Slotted Aloha) based anti-collision algorithms resolve the collision among the RFID (Radio frequency-ID) tags by adjusting the frame size for the incoming frame according to the number of un-identified tags. The system efficiency directly depends upon the estimated number of tags that contribute towards the frame size adjustment. In this paper, we propose an improved scheme ...

Tags/s - RFID reader-tag communication throughput using Gen2 Q-algorithm frame adaptation scheme

Radio Frequency Identification (RFID) became the most popular and used technology for items identification and tracking. Typical scenario of its application is a pallet of products bearing RFID tag, which passes by portal equipped with RFID antennas. In such scenario it is important to identify all tags as soon as possible. Access control mechanism widely used in RFID system is Dynamic Framed S...

Q+-Algorithm : An Enhanced RFID Tag Collision Arbitration Algorithm

Emerging applications of RFID require high e–ciency of tag identiflcation. Since passive tags have dumb functionality, the efflciency of tag identiflcation in RFID system relies on the performance of the collision arbitration algorithm embedded in a reader. In this paper, we develop a novel collision arbitration algorithm, which is named Q-Algorithm, improving Q-Algorithm which is introduced in...
