FRAME SYNCHRONIZATION SYSTEM AND METHOD USING THE ORTHOGONAL GOLD SEQUENCE FOR OFDM NETWORK

摘要

PURPOSE: A frame synchronization system and a method thereof are provided to improve data rate by inserting an orthogonal gold sequence of a small data size such as 32 bit or 64 bit to a frame. CONSTITUTION: An inverse fourier transform part(14) performs an inverse fourier transform about a transmitting object data related to specific user. An orthogonal gold sequence inserting part(16) inserts an orthogonal hold sequence to a frame of an OFDM signal generated by a result performed in the inverse fourier transform part. A transmitting part(18) transmits the OFDM signal to a corresponding receiving device. The orthogonal gold sequence is one orthogonal gold sequence or two same orthogonal gold sequences.
