PACKET TRANSMITTING METHOD FOR DECREASING EFFECT OF IMPULSIVE NOISE BASED ON MULTI-CARRIER

摘要

PURPOSE: A method for transmitting a multiple carrier-based packet is provided to restore damaged data in case of data in a pre-set domain is damaged using data with the same value as the damaged data in other domain while a packet with the damage data is received. CONSTITUTION: Packet data or 0 is allocated to a plurality of sub-carriers with respect to a long symbol or a data symbol in order to secure an identical infinite value in the long symbol or the data symbol forming a packet(S410). The allocated symbol is converted into a time domain(S420). A transmitter converts the symbol of a frequency domain into the symbol of a time domain. Using an inverse fast Fourier transform. The converted preamble, long symbol, and data symbol are transmitted to a receiver(S430).
