PURPOSE:To improve the transmission efficiency in response to required power by providing a transmission power control circuit. CONSTITUTION:A multiplex signal corresponding to each transmission objective station is arranged into a time series by a control signal of a burst control circuit 15 at a multiplex circuit 14 in response to the presence of an unnecessary transmission objective station, scrambled at a scramble circuit, and an output of a carrier wave generating circuit 18 is modulated by a modulation circuit 17, a signal level is suppressed as to a time region modulated only by a random code series signal corresponding to the unnecessary transmission objective station at a transmission power control circuit 19 and amplified to a prescribed level at an amplifier 20. |
