  • Direct digital sequence detection and equalization
    Patent number: 11876652
    Abstract: Methods and apparatuses for direct sequence detection can receive an input signal over a communication channel. Next, the input signal can be sampled based on a clock signal to obtain a sampled voltage. A set of reference voltages can be generated based on a main cursor, a set of pre-cursors, and a set of post-cursors associated with the communication channel. Each generated reference voltage in the set of reference voltages can correspond to a particular sequence of symbols. A sequence corresponding to the sampled voltage can be selected based on comparing the sampled voltage with the set of reference voltages.
    Type: Grant
