摘要： Methods and systems for detecting a guard interval size in a received OFDM signal are provided. A correlation calculator calculates a preliminary correlation signal based on a digitized signal, and generates a correlation signal corresponding to each possible guard interval size by summing the preliminary correlation signal in accordance with the possible guard interval size. Characteristics such as maximum value NM and number of points above a threshold Np in a sample period for each correlation signal are determined and compared, and the actual guard interval size is selected according to the determined characteristics.
