Claim 7:
8. A receiver to compensate for linear impairments, the receiver comprising:
an Rx signal comprising an asymmetric response of a satellite filter;
a pre-equalizer to pre-equalize the Rx signal with a coefficient; and
a demodulator to demodulate the Rx signal after the pre-equalizer;
a UWP (Unique Word Processor) to detect a Pre-Equalizer PLS (Physical Layer Scrambling) code in a PL header embedded in the Rx signal;
a memory to capture a received training sequence after the detection; and
a software processor to compute the coefficient to converge the received training sequence with a known sequence and to update the coefficient of the pre-equalizer to the computed coefficient.
