An Improved All Digital Timing Tracking Loop in OFDM Systems
When all digital phase-locked loop (PLL) is applied in OFDM systems, there are two important problems that must be solved, namely how to normalize the error signal and how to avoid the phenomenon of out-of-lock in multipath fading channel. This paper has studied the two problems and put forward a suitable solution scheme. The studying results show that the proposed scheme can really effectively solve the problem of timing tracking for OFDM systems and make PLL work normally in multipath fading channels.
