The effect of different algorithms on multi-tag recognition performance

Description:
1.) The above picture is the measured performance comparison chart (with the English frequency dynamic Q anti-collision algorithm as the comparison standard)。
2.) The above picture shows the performance comparison of the first round of inventory.。
3.）Testing with different algorithms on the same hardware platform。

	Algorithm name	Algorithm description
	Standard fixed Q anti-collision algorithm	The standard algorithm of the 18000-6C protocol. Performance is significantly reduced when the number of tags is large. *When the number of labels is small, it is not efficient.
	Impinj Dynamic Q anti-collision algorithm	American IMPINJ company's algorithm Good efficiency when the number of labels is large or small. *A portion of the performance was sacrificed for compatibility.
	I – Search Dynamic Q Anti-Collision Algorithm V1.0	Based on the dynamic Q algorithm of the American IMPINJ company. After optimization, the performance is slightly improved. *This algorithm is used in firmware versions 6.6 and below.
	I – Search Dynamic Q Anti-Collision Algorithm V2.0	Based on the dynamic Q algorithm of the American IMPINJ company. The new data model has greatly improved performance; this algorithm is used in firmware versions 6.7 and above. *The difference from the traditional algorithm can be clearly felt; the performance difference is more obvious when the number of tags is large.
