摘要
PURPOSE: A TDS-OFDM(Time Domain Synchronous Orthogonal Frequency Division Multiplexing) transmitter system is provided which has a 3600-point IDFT(Inverse Discrete Fourier Transform) processor to be realized easily in a hardware, and its signal processing method is also provided. CONSTITUTION: A FEC(Forward Error Correction) part(120) codes an OFDM signal in a frequency domain to sense an error in a receiver side and to correct the error. A mapping part(210) maps the coded OFDM signal in a frequency domain by a mapping method. A 3600-point IDFT part(400) modulates the OFDM signal in a frequency domain comprising 3600 parallel data into an OFDM signal in a time domain having 3600 sample data. A guard interval insertion part(240) inserts a guard interval to a front of the OFDM signal in a time domain. A synchronous information insertion part(250) inserts a synchronous signal for synchronization and channel equalization of a transmitter and the receiver to the OFDM signal in a time domain where the guard interval is inserted. And a forming filter part(260) performs a forming filtering of the synchronous signal inserted to the OFDM signal in a time domain.
