Abstract: The current document is related to the equalization of digital communications signals, including GB 20600-2006 and ATSC digital television signals, and is directed to methods that initialize adaptive filters for processing payload data within equalizers. These methods may operate at a clock speed faster than the symbol transmission rate and are applicable to a multitude of digital communications standards and protocols. In certain implementations, the initialization method generates input records, from output of a pseudorandom number generator, and output records, from the output of a pseudorandom number generator and a channel estimate, that are decoupled from transmitted and received data and are used to adjust equalizer coefficients to an initialization setting suitable for processing payload data.

Abstract: Certain embodiments of the present invention encapsulate a variety of data, for example, FIC data, together with ATSC-M/H Service data, into a single IP stream, to simplify the interface between demodulator and media processor. A single data interface protocol within the receiver can then be used, facilitating integration.
