An OFDM transmitter capable of inserting PN(Pseudo Noise sequence) into an OFDM symbol by adjusting size of the PN and a method of transmitting an OFDM signal are provided to insert PN information into the OFDM symbol, thereby transmitting the OFDM symbol. An FEC(Forward Error Correction) ...
transmitter inserting pseudo noise sequence into OFDM symbols after controlling the size of the pseudo noise sequence, and a method for transmitting OFDM signals are provided to accurately synchronize received OFDM signals and estimate a channel, thereby more accurately restoring the received OFDM signals...
