MOBILE STATION, BASE STATION, COMMUNICATION SYSTEM, TRANSMITTING METHOD, RECEIVING METHOD, CORRESPONDENCE PROCEDURE, IQ MULTIPLEXER, AND IQ MULTIPLEX METHOD
Document Type and Number:
Japanese Patent JP3919787
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a mobile station which can suppress jamming to an adjacency frequency band by suppressing the occurrence of the distortion of an amplifier, a base station, a communication system, a transmitting method, a receiving method, a communication method, an IQ multiplexer, and an IQ multiplexing method.
SOLUTION: When a scramble part 54 carries out an IQ multiplexing of output signals of a spreading unit 52 and a distributor 53 to form complex signals (I signal, Q signal), a signal power of I-axis and a signal power of Q-axis are considered to determine an amplitude factors βcc(I) and a βcc (Q) for ADPCCH (I).
