ABSTRACT:
A communications channel includes a buffer configured to store data. The data includes a plurality of symbols. A data dependent scrambler is configured to select a non-zero symbol and compare the non-zero symbol to each of the plurality of symbols stored in the buffer. In response to the non-zero symbol being different than each of the plurality of symbols stored in the buffer, the data dependent scrambler is further configured to generate a scrambling sequence to be used in scrambling the data, and the non-zero symbol is a seed of the scrambling sequence.
