An exemplary apparatus comprises a tuner for receiving a layered signal and producing a layered in-phase signal and a layered quadrature signal therefrom, an analog-to-digital converter for digitizing the layered in-phase signal and the layered quadrature signal and a processor for decoding the layered in-phase signal and the layered quadrature signal to produce one or more discrete layer signals.

Equalizers For Layered Modulated And Other Signals

US Patent:
7184473, Feb 27, 2007
Filed:
Oct 22, 2003
Appl. No.:
10/691133
Inventors:
Ernest C. Chen - San Pedro CA, US
Tung-Sheng Lin - Claremont CA, US
Weizheng Wang - Rancho Palos Verdes CA, US
William C. Lindsey - Pasadena CA, US
Assignee:
The DirecTV Group, Inc. - El Segundo CA
International Classification:
H03H 7/30
US Classification:
375229
Abstract:
A method and apparatus for equalizing digital data signals is disclosed. The method comprises the steps of demodulating and decoding an input signal having input data to produce a data output, remodulating the data output to produce a training sequence including an idealized input signal, wherein the training sequence is comprised of adjacent symbols in the input data, and generating equalizer parameters from the training sequence.
