<p>PROBLEM TO BE SOLVED: To provide a mobile radio terminal that can reduce the effect of a transmission path estimate error due to interference or noise and enhance the reliability of the amplitude of a synthesized output even when a different control method is adopted for transmission power of a common signal and that of an individual signal. SOLUTION: Pilot signal receivers 11-1n obtain transmission path estimate values h1(t)-hn(t) and their conjugate complex values h1*(t)-hn*(t), on the basis of a common pilot signal CPICH. Complex multipliers 21-2n multiply the conjugate complex values h1*(t)-hn*(t) by an individual signal DPCH of transmission paths p1-pn to carry out synchronization detection and weighting of maximum ratio synthesis. A normalization coefficient arithmetic section 40 obtains a normalizing coefficient (a), with respect to the amplitude on the basis of the conjugate complex values h1*(t)-hn*(t). A synthesis section 30 applies diversity synthesis to outputs from the complex multipliers 21-2n. A normalizing section 50 multiplies the normalizing coefficient (a), obtained by the normalization coefficient arithmetic section 40, to carry out normalization.</p> |
