Introduction: Chia Chan Chang is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of data transmission, particularly in orthogonal frequency division multiplexing (OFDM) systems. His innovative approach aims to enhance transmission efficiency through advanced packetizing methods.

Latest Patents: Chia Chan Chang holds a patent for a "Method and apparatus for independent packet and OFDM boundaries." This invention discloses methods and apparatus for data packetizing in an OFDM system. The invention allows packets to cross OFDM block boundaries, thereby improving transmission efficiency. A Frame Delimiter (FD) with a predefined format is inserted at the start of each packet to indicate its beginning. The FD can consist of a predefined bit pattern or modulation points of a modulation constellation. Additionally, idle data can be inserted into OFDM blocks when no packet is ready, and measures are taken to avoid generating the predefined bit pattern when data contains it.
