The present invention provides methods and apparatus for detecting a master synchronization sequence. The method includes: calculating the length of each local primary synchronization sequence length of the received signal in the same continuous sample sequences and each local primary synchronization sequence cross-correlation value; the samples of each of the continuous sample sequence for each sample point by calculating cross-correlation value for normalized to calculate the normalized cross-correlation value; according to the calculated maximum normalized cross-correlation value to determine the location and type of primary synchronization sequence of the received signal in the. Through the technical scheme of the invention can affect the detection process in the main sequence at least partially reduce the various factors, such as carrier frequency offset, uplink interference from other terminals and / or parts of DC interference etc..
