A method for producing a basic ban signal via the broadcast radio frequency - the performance, the corresponding device and the transmit station

摘要

The present invention relates to a method of generating a signal in baseband (vp) representative of the power emitted by a transmitter station. This baseband signal is used in particular for controlling the power of emission in a transmitter station. According to the invention, a portion (s) of the radio frequency signal (s) emitted by the transmitting station is extracted, and then mixed with it - even in order to generate a signal (s) of voltage having at least one continuous component. The signal (s) of voltage is then filtered and finally amplified according to a logarithmic function. Fields of application to mobile radio telecommunication systems
