The present invention discloses a long term evolution LTE system the initial automatic gain control AGC method and apparatus, the method comprising: measuring at a first predetermined time interval and the average power of the received transmission signal; calculating an average power with a preset ...
and its use in the feedback circuits of vacuum tube oscillators dates back to the 1930s. The incandescent bulb is used in the negative feedback path as an automatic gain control; the tungsten filament’s initial low resistance makes for high gain to kick off oscillation, after which it heat...
Disclosed are a method and device for setting an initial automatic gain control (AGC) gain. The method comprises: in each average power calculation period, obtaining receiving signal power of each OFDM symbol in the average power calculation period; according to a receiving signal power difference ...
Enablement of an AFC Defeat signal defines an initial interval during which the IF gain is maximum. When the AFC Defeat signal becomes inactive, the receiver is operated in a non-coherent mode in which the gain of the IF amplifier is reduced incrementally whenever the IF signal exceeds a ...
(AGC) in a base station in several ways depending on the availability of certain information such as the relationship between signal and int Erferencia (SIR), Growth Factors and other parameters.It implements a more accurate estimate of the word initial control of an adjustable gain Amplifier ...
