Abstract
A method and apparatus for detecting the transmitted mode and guard interval length. The mode detection is adopted by the DVB-T system to increase system flexibility and combat multi-path interference in the transmission environment, of the received OFDM signals by applying the concepts of down-sampling and correlation. The unique combination of down-sampling and correlation method requires far less memory than the traditional correlation methods. By comparing the indicators resulting from output of each correlation module, the transmitted mode and guard interval length are detected with much greater reliability.
