PROBLEM TO BE SOLVED: To reduce arithmetic amount for carrier synchronization in a mobile station that receives a transmission symbol. SOLUTION: A received wave from an antenna is linearly weighted and synthesized, a feedback symbol signal and a feedback filter coefficient are convolved, the resulting signal is discriminated and a discrimination result is outputted, a discrimination means outputs an error signal accompanying signal discrimination, the feedback symbol signal and a parameter estimate symbol, and weighting coefficients and a feedback filter coefficient are estimated to minimize the error signal. A transmission symbol is outputted as a transmission distortion signal or a transmission training signal period, the feedback filter coefficient is convoluted (32) with a delayed transmission distortion signal for the transmission data period and the result is subtracted (33) from the transmission symbol and a discrete complex number is added so that the power is a prescribed value or below to obtain the transmission distortion signal (35), a weight of linear weight synthesis is given and the signal is converted into an RF signal and it is transmitted.
