Abstract
An IF receiver receives a tapped portion of a modulated communication signal. A processor, local with respect to the IF receiver, receives an interrupt from a main processor instructing it to evaluate the power levels of desired and undesired components of the communication signal. The interrupt may be sent for a variety of reasons, such as according to a predetermined schedule, or in response to changes in a communication network, such as new equipment installation and temperature changes. The local processor instructs the IF receiver to tune it's LO so that the evaluation range of the receiver and feedback loop to parameter-adjustable components includes the frequency, or frequencies, of a specified signal component. The local processor evaluates the power level of the specified signal component. Based on the evaluation, the local processor instructs parameter-adjustable signal processing components to alter parameters to optimize characteristics of the communication signal for transmission.
