Multi-protocol radio frequency identification transponder transceiver

A transceiver for a RFID reader and a transceiver for a RFID transponder (tag) allow communication between the two devices. The RFID reader utilizes an analog front end and a digital backend. In the receiver portion of the transceiver, the front end of the RFID reader uses a pair of down-conversion mixers to demodulate a received signal into in-phase (I) and quadrature (Q) components and analog-to-digital converters (ADC) digitize the signal. A digital signal processor (DSP) in the back end processes the digital signal and uses a matched filter for data detection. The RFID tag receives an inductively coupled signal from the reader and the receiver portion of the tag uses a pulse / level detector that employs an analog comparator and a sample and hold circuit to detect the received signal. A digital decoder / controller is used to decode the incoming data and to establish a sampling clock for the pulse / level detector. An automatic gain control (AGC) circuit adjusts a receiver gain according to the received signal strength and controls tuning of magnetic coupling circuitry.

Data detection and decoding system and method

A data detection and decoding system includes a SOVA channel detector that uses single parity (SOVASP) to improve the accuracy with which the detector estimates bits. Each column or row read back from the read channel constitutes a code word and each code word is encoded to satisfy single parity. Because the SOVASP channel detector detects whether each code word satisfies single parity, it is unnecessary to use both a column decoder and a row decoder in the channel decoder. Either the row decoder or the column decoder can be eliminated depending on whether bits are read back on a column-by-column basis or on a row-by-row basis. This reduction in components reduces hardware complexity and improves system performance. The output of the row or column decoder is received by a second detector that processes the output received from the decoder to recover the original information bits.

Data Detection For Visible Light Communications Using Conventional Camera Sensor

The invention relates to a detection system for determining data embedded into the light output of a light source in a form of a repeating sequence of N symbols. The detection system includes a camera and a processing unit. The camera is configured to acquire a series of images of the scene via specific open / closure patterns of the shutter. The processing unit is configured to process the acquired series of images to determine the repeating sequence of N symbols. By carefully triggering when a shutter of the camera is open to capture the different symbols of the encoded light within each frame time of a camera, a conventional camera with a relatively long frame time may be employed. Therefore, the techniques presented herein are suitable for detecting the invisible “high frequency” coded light while using less expensive cameras as those used in the prior art.
