[0078] see figure 1 , the existing tags in the RFID system are t1, t2, t3, t4, t5 and t6, the missing tags are t7, t8, t9 and t10, and the unknown tags are t11, t12, t13 and t14.
[0079] continue to see figure 1 , carry out the first round of unknown tag suppression on the above-mentioned radio frequency identification system, in the first round of unknown tag suppression process, the reading head sets the frame length f=N, N=10, generates a random number seed, and broadcasts the frame length and the random number seed . Each tag calculates the tag response time slot number after receiving the information broadcast by the above-mentioned reading head. The read head predicts the state of each slot and saves it in the f-bit vector EV 1 in, such as figure 1 The desired frame in . The reading head executes the frame, and each tag sends a 1-bit response information in the tag response time slot, and the reading head detects the actual state of each time slot, which is stored ...
