Abstract

A wireless communication method according to an embodiment includes precoding a stream of a transmission signal in a time domain by using an FIR filter, controlling a transmission power of the precoded stream, amplifying the precoded stream such that the controlled transmission power is obtained; and performing control for changing a tap length in precoding such that the tap length is decreased in a case where a magnitude of a last tap coefficient in precoding is small and the tap length is increased in a case where the magnitude is large, with respect to a threshold value calculated on the basis of quality information of a received signal fed back from a reception device that has received the amplified stream or quality information of a received signal calculated by using at least characteristics of an amplifier.
