1. A method of processing a digital stream of bits at a receiver, said method comprising:

  • receiving a bit stream at the receiver;

    detecting predetermined bit combinations at n-bit spacings in the bit stream;

    selecting, at the receiver, a subset of said bit stream having reduced data-pattern autocorrelations present in said subset of said bit stream relative to said bit stream by discarding bits of one or more given bit combinations when a number of the one or more given bit combinations exceeds a predetermined limit for the one or more given bit combinations relative to other of the predetermined bit combinations; and

    passing said subset of said bit stream from the receiver to an adaptation engine.
