    摘要: The present invention is related to systems and methods for enhancing data detection in a data processing system. In one embodiment, a data processing system is disclosed that includes a data detector circuit that is governed at least in part based upon selected coefficients. The selected coefficients are selected as either a first set of coefficients or a second set of coefficients where the second set of coefficients has fewer coefficients than the first set of coefficients.

    摘要: A method and system for eliminating/suppressing long transition runs over a communications channel is disclosed. The method may include providing modulation coding based on a multi-level finite state machine (ML-FSM) having a periodic structure, the periodic structure being defined by a predetermined number of time frames. The ML-FSM may include a plurality of penalty-free edges for connecting nodes in one time frame to nodes at the same level in a subsequent time frame and a plurality of penalty edges for connecting nodes in one time frame to nodes at an upper level in the subsequent time frame. The method may further include utilizing the ML-FSM based modulation coding to facilitate data transmission over the communications channel.

    摘要: Various embodiments of the present invention provide systems and methods for data processing. For example, data processing systems are disclosed that include a data decoding system. The data decoding system includes a data decoder circuit and a simplified maximum likelihood value modification circuit. The data decoder circuit is operable to apply a data decode algorithm to a decoder input to yield a first decoded output and an indication of at least one point of failure of the first decoded output. The simplified maximum likelihood value modification circuit is operable to identify a symbol of the first decoded output associated with the point of failure, and to modify a subset of values associated with the identified symbol to yield a modified decoded output.
