The invention, aiming at an OFDM (Orthogonal Frequency Division Multiplexing) wireless communication system, provides a timing synchronization algorithm which can be easily and simply implemented in a receiver. A 62-point frequency domain ZC (Zadoff-Chu)sequence is generated by a generation formula of a frequency domain ZC sequence, two ends of the generated sequence are added with 33 zeros, then, three zeros are inserted between neighboring points so as to expand the sequence to have 512 points, and synchronization sequence obtained by performing IFFT (Inverse Fast Fourier Transform) is usedas a synchronizing signal of the OFDM wireless communication system; the receiver firstly quantifies the received synchronization sequence, then, performs conjugated correlation with a local synchronization sequence, and simultaneously, calculates a cross correlation coefficient amplitude based on sum of absolute values of a real part and an imaginary part. In this way, the correlation operation and the cross correlation coefficient amplitude calculation only contain addition and subtraction, use of a multiplying unit is avoided, operation complexity is greatly reduced, processing efficiency is improved and resource is saved, so that the timing synchronization of the receiver can be implemented easily and simply, and can be implemented more effectively on receiver hardware.
