Transmission gain controlling method and radio apparatus

摘要

To prevent deterioration of the reception characteristic of communication partner station without increasing the circuit scale of the radio apparatus. Amplitude of a transmission signal subjected to inverse equalization processing by an inverse equalization processor 104 that provides a characteristic, which is opposite to a distortion characteristic on the radio propagation path received at a signal receiving time, with respect to the transmission signal is controlled based on any one of a square sum of all tap coefficient values of a digital filter, which is a channel estimation value, a square root of square sum, or a sum of absolute values.
