Abstract
A transmission system ( ) broadcasts a signal. Within the system ( ), a power amplifier ( ) causes non-linear distortion. A pre-amp component, such as a band-pass filter ( ), causes linear distortion. A high power filter ( ) is located downstream of the power amplifier ( ) and causes linear distortion. A linear equalizer ( ) compensates for the distortion caused by the high power filter ( ). A non-linear corrector ( ) compensates for the distortion caused by the power amplifier ( ), and is located downstream of the linear equalizer ( ). A linear equalizer ( ) compensates for the distortion caused by the pre-amp components (e.g., ). The compensating components ( ) are located upstream of the distorting, pre-amp component (e.g., ). A interpolation component ( ) is located between the three compensating components ( ) and the distortion causing components ( , and ) to increase a rate of the signal, such that the compensation occurs at a lower rate of the signal. Signal sampling points ( ) are located downstream of each distorting component ( , and ). Sampling selectively occurs at one of the sample points ( ) for use to update compensation.
