Abstract
A hardware control loop (19) derives an AGC setting for a communication receiver based on signal strength information (16), without incurring program execution delay of a baseband processor.
Claims29
An automatic gain control apparatus, comprising:
- a first input for receiving from a communication receiver information indicative of signal strength of a received communication signal;
- and
- hardware coupled to said first input and responsive to said signal strength information for determining an automatic gain control setting for the communication receiver without incurring program execution delay of a data processor.
A communication receiver apparatus, comprising:
- a receiver portion for receiving and processing communication signals;
- and
- a control portion for determining an automatic gain control setting for said receiver portion, said control portion including a first input coupled to said receiver portion for receiving therefrom information indicative of signal strength of a received communication signal, said control portion further including hardware coupled to said first input and responsive to said signal strength information for determining said automatic gain control setting without incurring program execution delay of a data processor.
An automatic gain control method, comprising:
- providing information indicative of signal strength of a communication signal received by a communication receiver;
- and
- responsive to said signal strength information, determining an automatic gain control setting for the communication receiver without incurring program execution delay of a data processor.
