Abstract
In a receiver, a digital automatic gain control circuit receives a series of digital samples representing at least one of an in-phase component and a quadrature component of a received signal, and provides scaled in-phase components and scaled quadrature components to an equalizer. The digital automatic gain control circuit includes a gain updating unit that receives a value representing at least one of an in-phase component and a quadrature component, receives a target reference value, and updates a gain value based on a difference therebetween. The digital automatic gain control circuit also includes a scalar that scales the received signal based on the updated gain value.
