Abstract
A mobile communication terminal calculates an interference rejection combining reception weight matrix based on a vector representing a reference signal transmitted from a desired base station so as to reduce interference with a desired beam of radio waves. The mobile communication terminal estimates, from the interference rejection combining reception weight matrix and the reference signal, an all received power expected when an IRC is implemented, and estimates, from an interference rejection combining weight vector, a channel matrix, and a reference signal sequence, a desired reference signal power expected when an IRC is implemented. The mobile communication terminal subtracts the desired reference signal power from the all received power, thereby estimating an interference and noise power expected when an IRC is implemented, and calculates an SINR expected when an IRC is implemented from the estimated interference and noise power.
