More Information
Summary:A signal receiving system, a band detection method for a multi-carrier signal and a demodulating apparatus thereof. Each carrier of the multi-carrier signal has a plurality of symbols respectively corresponding to a plurality of time. The band detection method includes: defining a scan area range according to a full band range of the multi-carrier signal; obtaining a reference symbol corresponding to each of the symbols according to time and frequency offset values in the scan area range; performing an operation on each of the symbols and corresponding reference symbol to obtain calibration information of each carrier of the multi-carrier signal; tuning the full band range of the multi-carrier signal according to the calibration information thereof.
