Abstract
Symbol timing offset in OFDM systems does not only induce intersymbol interference (ISI) but also causes phase rotation of the signal constellation of the receiver FFT output, which degrades system performance. In this paper, we describe a patent-pending coarse and fine symbol timing recovery algorithm for OFDM systems which, unlike previous algorithms [l-51, does not require carrier synchronization nor supplementary pilot signals for proper operation.
