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...
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) ...
