Mobile communications terminal and radio communications system

A mobile communications terminal divides a plurality of multipath signals associated with radio signals transmitted from a plurality of base stations 5 using an S-CCPCH into groups by base station, i.e., by transmit source, maximum-ratio-combines a plurality of multipath signals associated with each same base station 5 which is a transmit source into a composite signal, decodes the composite signal, and selects a composite signal having a good decoded result from among decoded composite signals.
