| Abstract | Provided are a transmitter and a frequency hopping method thereof. The transmitter includes: a channel encoder outputting a bit stream of encoded information data; a symbol mapper outputting a symbol stream obtained by constellating the bit stream; a frequency allocation and hopping part determining a frequency to be allocated to the symbol stream; and a multi- carrier modulator loading and outputting the symbol stream output by the frequency allocation and hopping part on a multi-carrier, wherein the frequency allocation and hopping part comprises a logical frequency mapping part determining a frequency capable of optimally averaging adjacent cell interference, and a physical frequency mapping part mapping the determined frequency one-to-one and determining a frequency. |
