METHOD FOR GENERATING BASEBAND SIGNAL EXPRESSING TRANSMITTED RADIO FREQUENCY POWER, DEVICE, TRANSMITTING STATION AND TELECOMMUNICATION SYSTEM FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for generating a baseband signal (Vp) which expresses power transmitted by a transmission station. SOLUTION: According to this invention, a part (S') of a radio frequency signal S transmitted by the transmission station is extracted, and next, by mixing that part with the signal itself, a voltage signal (S") having at least one DC component is generated. The voltage signal (S") is filtered and is ultimately amplified, while using a logarithmic function. This method is applicable to a mobile radio electric communication system.
