Abstract
A mobile station for preventing reduction of the line quality when it is used near the head of a human operator. Plural antennas are arranged so that the cross-correlation of the received waves becomes small. The signals received by the antennas are delayed by a delay time to prevent interference between the received signals so that the time difference of each received signal becomes at least one chip time of the spreading code or more. After that, a combiner combines the received signals, and an output signal of the combiner is inputted into a rake receiver. A reduction of the extent of the delay spreading is prevented by directivity of the antennas in use near a human body, and a decline of path diversity gain by the rake receiving is reduced.
