  • Publication number: 20080006702
    Abstract: 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.

  • Publication number: 20070296590
    Abstract: RFID readers, systems, and methods are provided for overcoming the effects of RF interference. While a system is communicating in a channel, RF interference is monitored. If it is low, then the next channel to be hopped onto is chosen in an unbiased manner. But if interference is high, then the next channel to be hopped onto is chosen in a biased manner that disfavors at least one channel over another, in view of the detected interference. The choice of the next channel can thus result in diminishing communication in channels with a lot of RF interference.

  • Publication number: 20070296603
    Abstract: RFID readers, systems, and methods are provided for overcoming the effects of RF interference. While a system is communicating in a channel, RF interference is monitored. If it is low, then hopping to another channel is performed according to an ordinary decision. But if interference is high, then hopping out to another channel can be earlier than would be dictated by the ordinary decision under the same circumstances. The earlier hopping out can result in diminishing communication in channels with a lot of RF interference.

  • Publication number: 20070164851
    Abstract: RFID tag responses are detected by an RFID reader system. The tag response may be detected based on a reference measurement during a tag silent period and another one during the tag response. This helps determine whether a slot is empty or occupied, in a slotted aloha algorithm. The result is reported to the Q-algorithm for a better decision.

  • Publication number: 20070109129
    Abstract: 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.

  • Publication number: 20070046432
    Abstract: Radio frequency identification (RFID) tags selected for inventorying using combination of preselect and/or post select criteria. The selection commands can be for selecting according to a tag memory content, by invoking the mask address or by comparing other tag characteristics. Selection criteria can be determined locally at a modem block of a reader or provided to the modem block by higher layers of the reader. Tags meeting the selection criteria are reported to the higher layers for further actions. Some tags may be held while waiting for instructions from the higher layer block(s).

  • Patent number: 7164734
    Abstract: A decoder of a data signal subjected to phase shifting keying (PSK) modulation uses a plurality of phase locked loops (801-1 to 801-n) having an inner decoder for short block codes, at least one of which is adapted to apply excess processing power to process a selected burst of the data signal, such as processing the burst with multiple initial phase/frequency error estimates. A selection circuit identifies the burst and supplies to said one of said plurality of phase-locked loops (801-1 to 801-n) for re-processing the bust with excess processing power. An outer Reed-Solomon block decoder (319) may be used to correct errors in the codewords from the phase locked loops and may be used in the selection of the burst by the selection circuit.

  • Publication number: 20060211386
    Abstract: A transmitter shifts a baseband data signal having a bandwidth of 2?M using a tone signal having a frequency ?M, which centers a sideband of the data signal at zero frequency. The transmitter then filters the shifted signal to filter out the non-centered sideband, and then adds the tone signal to form a composite signal. The transmitter upconverts the composite signal during a first operational mode using a RF signal having a frequency ?C equal to a center frequency of a channel. In a second operational mode, the transmitter upconverts a DC level using the same RF signal. The upconverted DC level can be used as a continuous wave carrier signal having a frequency ?C. The transmitter has a single RF oscillator to output both a SSB signal centered at frequency ?C during the first mode and a carrier signal of frequency ?C during the second mode.

  • Publication number: 20060199551
    Abstract: A transmitter upconverts a SSB data signal during a first operational mode using a RF upconverting signal having a frequency that is offset from a center frequency of a channel (?C) by an amount that depends on the data signal's SSB bandwidth (?M). In a second operational mode, the transmitter upconverts a tone signal having a frequency ?M using the same RF upconverting signal. The upconverted tone signal can be used as a continuous wave (CW) carrier signal having a frequency ?C. The transmitter has a single RF oscillator to output both a SSB signal centered at frequency ?C during the first mode and a carrier signal of frequency ?C during the second mode.

  • Patent number: 7068974
    Abstract: A downlink beam frame signal processing system (100) for a communication satellite includes a packet switch (608) that routes self addressed uplink data to a memory (804). The memory (804) stores queues for at least a first and a second downlink beam hop locations (302, 304). The processing system (100) also includes a power amplifier (108) that amplifies a waveform formed using the uplink data. A power gating circuit (1200) coupled to the power amplifier (108) includes a power gate input (1216) responsive to a power gating signal to remove RF power from at least a portion of the waveform before transmission.

  • Publication number: 20060133140
    Abstract: An RFID tag has a Non Volatile Memory (NVM) array that can store data in a way that survives loss of power. The data is configuration data that controls the operation of an operational component of the tag. A performance of the operational component is thus adjusted according to the configuration data, and the adjustment is retained.

  • Publication number: 20060133175
    Abstract: An RFID tag has a fuse that is adapted to store configuration data in a way that survives loss of power. The fuse can be one time programmable or many times programmable, and be implemented with a non-volatile memory. The configuration data becomes available to an operational component of the tag, such as at power up, controlling its performance.
