PURPOSE: A signal receiving device of a communication system using a multicarrier transmission method and interference cancelling method of the signal receiving device are provided to efficiently distribute an operation amount which can be processed during an interference cancelling process, thereby increasing receiving performance. CONSTITUTION: An ISI(inter-symbol interference) controller(100) cancels interference between symbols from a received signal with delay time which is larger than a guard interval. An ICI(inter-carrier interference) controller(106) cancels interference between sub carriers in a symbol on a frequency domain from the received signal. The ISI controller generates a replica about a previous symbol on a time domain. The ICI controller cancels interferences between symbols as well as sub carriers by generating a replica for a current symbol. |
