Patent ID: 8908754

Claim:
A method comprising: receiving, via a channel, signals representing respective bit patterns of a discrete set of multiple possible bit patterns capable of being received via the channel, the signal having amplitude loss across frequencies of a frequency band of the signal or interference caused when the signal passed through the channel, the receiving performed until signals representing each of the multiple possible bit patterns are received; determining, for the signals received, which bit patterns represented by respective ones of the signals have been used to adjust one or more equalizing coefficients a predetermined number of times and which other bit patterns represented by respective others of the signals have not been used to adjust the one or more equalizing coefficients the predetermined number of times; disregarding the respective signals responsive to determining that the bit pattern represented by the respective signals have been previously used to adjust the one or more equalizing coefficients; and adjusting, based on the other bit patterns, the one or more equalizing coefficients responsive to determining that the other bit patterns represented by the respective other signals have not been used to adjust the one or more equalizing coefficients the predetermined number of times.
