Research of a novel feedforward AGC optical receiver
Indispensable for high quality optical carrier signal reception in a large dynamic range
AGC analog optical receivers are widely used in the optical transmission of radio and microwave signals
such as fiber CATV
direct broadcast satellite TV
wireless communication and radar.By using a new optical input power level detection and signal treatment method to control the gain of the receiver and keep its output level within the required range
a novel feedforward AGC optical receiver without radio frequency feedback circuits is realized.
