摘要： An RFID reader inventories a population of tags. The reader evaluates responses from tags by categorizing them in slots. As tags are inventoried, the number of slots based on a Q-parameter is reduced. The reader addresses the tags by communicating a Q1 value for the Q parameter, generates first contents from replies received from the tags, and computes a first merit statistic based on the first contents. Then, the reader repeats the process with a Q2 value. Upon computing the first and the second merit statistics, the reader determines a Q3 value for the Q parameter. If the Q3 value is substantially equal to the Q1 value, the reader continues to receive the second replies without communicating the Q3 value. If the Q3 value is different from the Q2 value, the reader uses the Q3 value for another round of iteration heuristically converging on an optimum Q value.

As tags are inventoried, the number of slots based on a Q-parameter is reduced. The reader addresses the tags by communicating a Q1 value for the Q parameter, generates first contents from replies received from the tags, and computes a first merit statistic based on the first contents. Next, the reader determines a Q2 value for the Q parameter, which if used in the same way would meet a preset fairway condition better than the first merit statistic. After determining the Q2 value, the reader addresses a portion of the tags by communicating the Q2 value for the Q parameter.

摘要： RFID system components, such as readers and tags, communicate where the reader inventories a population of tags. The reader evaluates responses from tags by categorizing them in slots. As tags are inventoried, the number of slots based on a Q-parameter is reduced. The reader determines an interim value for the Q parameter, generates a Q1 value by applying the interim value to a damping function, and uses the Q1 value in another round of interrogation. The reader then determines whether to increase or decrease the interim value depending on the tag replies. The increase or decrease may be an increment or a decrement such as incrementing or decrementing a floating point number of the interim value in a damping function that is arranged to return an integer by rounding the floating point number.

摘要： RFID system components, such as readers and tags, communicate where the reader inventories a population of tags. The reader evaluates responses from tags by categorizing them in slots. As tags are inventoried, the number of slots based on a Q-parameter is reduced. The reader reduces the Q-parameter first in a first manner, then in a second manner where the second manner is different from the first manner. The first manner and the second manner may be different algorithms, different subroutines of an algorithm, or the same damping algorithm with different damping parameters.

摘要： RFID system components, such as readers and tags, communicate where the reader inventories a population of tags. The tags choose randomly one of a plurality of slots in response to each one of the values communicated by the reader and reply according to their chosen slot. The reader may initiate the inventorying by determining a Q-parameter value from a stored value and communicating the Q-parameter value to the tags. The reader may evaluate replies received from the tags in another plurality of tags, determine a second value from evaluating the second replies, and store the second value for future use.

摘要： RFID system components, such as readers and tags, communicate by a reader transmitting waveforms that encode a calibration symbol and a divide ratio. Tags include a processor to determine a backscatter link period result by dividing a count value representing the calibration symbol by the divide ratio and adding an adjustment. Tags modulate a backscatter waveform that includes symbols using a link period determined from the result.

摘要： RFID tags are commanded to generate a pilot tone in their backscatter. When the backscattered pilot tone is received in the reader, the pilot tone is used to estimate the tag period/frequency. Then, the estimate is used to seed and lock a symbol timing recovery loop, which provides a detected signal to one or more correlators for detecting the tag preamble. A delayed version of the received tag signal is compared against a baseline signal threshold established from the received signal to detect the pilot tone.
