- In this paper, an adaptive digital Frequency Phase Locked Loop (FPLL) algorithm is proposed to improve the carrier recovery performance of 8-VSB receiver. The proposed carrier synchronization technique not only provides a robust 8-VSB DTV reception in fixed and indoor environments, but also makes it possible to watch the HDTV in portable environment. This is because the proposed technique dramatically reduces tracking jitter and acquisition time and enlarges acquisition range by adopting a sign detector, pilot extract filter bank, adaptive lock detector, mode selector, and loop filter bank to the conventional FPLL algorithm. © 2005 IEEE.
