Claim 0:
1. A non-transitory computer-readable storage medium having instructions embodied thereon, the instructions being executable by one or more processors to perform a method for compensating for linear impairments at a receiver, the method comprising:
receiving an Rx signal comprising an asymmetric response of a satellite filter;
pre-equalizing the Rx signal with a coefficient;
demodulating, after the pre-equalizing, the Rx signal;
detecting a Pre-Equalizer PLS (Physical Layer Scrambling) code in a PL header embedded in the Rx signal;
capturing a received training sequence after the detecting;
computing the coefficient to converge the received training sequence with a known sequence; and
updating the coefficient of the pre-equalizing to the computed coefficient.
