摘要

The invention concerns a method for automatic regulation of the amplification of a dispersed spectrum receiver with direct sequence dispersion, whereby the amplification is regulated by the use of a digital AGC system 8, and a dispersed spectrum receiver with direct sequence dispersion. According to the invention, threshold power detection is carried out on the received signal of an RF or medium frequency signal, where the output value of the threshold power detector is compared with predetermined set values and where using sizes derived from the differences in values the amplification of the receiver is regulated in a direction determined by the threshold power detection before the signal is taken to the digital AGC system 8.
