Classification: H04L

Abstract:
An apparatus for blind automatic gain control in a digital communications device comprising:a gain error evaluator responsive to an input baseband signal and a sliced version of said input baseband signal and operable to generate a gain error signal in accordance with said input baseband signal and said sliced version of said input baseband signal;a maximum value detector operable to generate a renew signal in accordance with said sliced version of said input baseband signal and a first predetermined reference value;a gain value adjuster responsive to said gain error evaluator and said maximum value detector and operable to converge said gain error signal in a first state using a first convergence technique and further operable to converge said gain error signal in a second state using a second convergence technique; andsaid gain value adjuster further operable to generate an output gain value signal from said converged signal.
