Abstract
The orthogonal frequency division multiplexing (OFDM) technique has been adopted for the European digital terrestrial broadcasting standard, which is called the digital video broadcasting for terrestrial (DVB-T). In this paper, we propose a new symbol timing recovery algorithm for the (OFDM) system to achieve a fast start-up using the scattered pilots under the frequency offset, the common phase error, and severe noise. With the proposed algorithm, we can detect up to /spl plusmn/35 sample offsets and can recover the sampling timing phase even in the carrier frequency offset of up to /spl plusmn/0.35 OFDM subcarrier space. So, we can much reduce the start-up time by simultaneously operating both the carrier and symbol timing recovery loops.
