PROBLEM TO BE SOLVED: To reduce a peak factor of a multiplex signal in a multiplexer for an amplitude modulation frequency hopping signal and an amplitude modulation quadrature frequency division multiplex(OFDM) signal multiplexer. SOLUTION: In the signal multiplexer, a phase means 21i is provided to each path between an amplitude modulator 2i and a means 8 for forming power, and a phase shift of a phase shift means 21i is controlled in response to an oscillated frequency of a frequency synthesizer 4i so as to reduce a peak factor by a phase control means 22. A frequency hopping control means 7 gives oscillation frequency data to each frequency synthesizer 4i to the phase control means 22. |
