Abstract：
 This invention relates to a frame synchronous generating method in a time domain synchronous OFDM system including: 1, generating a m-sequence of 8 or 9 stages with a LFSR of Fibonacci type, 2, getting related PN sequence of the lengths of 420 or 945 signs by circulation expansion or patching ¡°0¡± directly, 3, plugging the PN sequence into frame head position of the TDS-OFDM hierarchical frame structure and transmitting the complete TDS-OFDM signals finally, in which, the PN sequences of each signal frame are the same and are not processed for phase shift.
