Algorithm for AGC index management against crowded radio environment
Morgane Joly Fabian Rivière Éric Renault
This paper describes a receiver that uses an innovative method to predict,
according to history of receiver operating metrics (packet lost/well received),
the optimum automatic gain control (AGC) index or most appropriate variable
gain range to be used for next packet reception, anticipating an interferer
appearing during the payload reception. This allows the receiver to have higher
immunity to interferers even if they occur during the gain frozen payload
reception period whilst still ensuring an optimum sensitivity level. As a
result, the method allows setting the receiver gain to get an optimum trade-off
between reception sensitivity and random interferer immunity.
