Patent ID: 8107520

Claim:
A wireless communication apparatus, comprising hardware equalizer which receives a transmission line estimation sequence, and generates a transmission line characteristic estimation value for each of a plurality of sub-carriers, and smoothes a transmission line characteristic estimation value of a target sub-carrier to be processed and the transmission line characteristic estimation value of an adjacent sub-carrier of said plurality of sub-carriers, wherein said equalizer comprises: a determination unit which determines whether or not said adjacent sub-carrier comprises a null sub-carrier, and a smoothing unit which smoothes the transmission line characteristic estimation value of said target sub-carrier by excluding the transmission line characteristic estimation value of said adjacent sub-carrier determined as a null sub-carrier by said determination unit, and wherein said smoothing unit substitutes the transmission line characteristic estimation value of a sub-carrier determined as a null sub-carrier by said determination unit, for the transmission line characteristic estimation value of said target sub-carrier to execute smoothing in said smoothing unit.
