Symbol synchronisation in a multicarrier receiver

摘要

High-frequency components are extracted from an OFDM signal. A symbol clock signal is generated in response to the extracted high-frequency components. Specifically, a sample clock signal is generated in response to the OFDM signal. A frequency of the sample clock signal is divided to generate the symbol clock signal from the sample clock signal. A timing of the frequency division is controlled in response to the extracted high-frequency components.
