Claim:
1. A receiving apparatus comprising: filtering circuitry which, in operation, receives a reception signal including a short preamble, the short preamble including a plurality of pilot subcarriers and a plurality of null subcarriers which are alternately mapped in a transmission band at predetermined frequency intervals, wherein the plurality of pilot subcarriers are intermittently mapped in a frequency domain and repeatedly mapped in a time domain; and correction circuitry which, in operation, corrects a carrier frequency error in the reception signal based on the plurality of pilot subcarriers out of the filtered reception signal, wherein the filtering circuitry allows signal components of the pilot subcarriers in the short preamble to pass therethrough and suppresses signal components of the null subcarriers in the transmission band.
