摘要：
A method for generating a preamble sequence using PN sequence in an OFDM communication system and a method for time synchronization and frequency offset estimation are provided. The method for generating a preamble sequence using a PN sequence at an OFDM transmission system includes the steps of: generating pseudo noise (PN) sequence having high autocorrelation value; and generating a preamble sequence by multiplying the PN sequence by an inverse matrix of an inverse fast Fourier transform (IFFT) matrix in frequency domain so as to make the PN sequence become the preamble sequence in time domain.
