Title: Innovations of Chih-Hung Lin
Introduction
Chih-Hung Lin is a notable inventor based in Tainan County, Taiwan. He has made significant contributions to the field of radio frequency identification (RFID) technology. With a total of 4 patents, his work focuses on enhancing the efficiency and effectiveness of RFID systems.
Latest Patents
One of his latest patents is titled "RFID reader and circuit and method for echo cancellation thereof." This invention provides an echo cancellation circuit for an RFID reader, which includes a gain calculator, a gain adjustment circuit, and a subtraction circuit. The gain calculator utilizes an adaptive algorithm to provide a complex gain value based on a carrier signal and a received signal. The gain adjustment circuit multiplies the carrier signal by this complex gain value, while the subtraction circuit subtracts the output of the gain adjustment circuit from the received signal, resulting in an output signal that effectively cancels echoes.
Another significant patent is the "Method and system for reading RFID tags." This invention outlines a method that begins with receiving a tag signal from the RFID tag. It involves recovering a data clock rate from the tag signal based on the statistics of pulse lengths. The method then determines a frame synchronization point of a data frame following a preamble in the tag signal through signal correlation. Finally, it decodes the data frame using an adaptive Viterbi algorithm on an extended trellis diagram, which is structured according to the modulation scheme and potential variations of the data clock rate.
