  • Decision feedback equalizer and method used in digital television receiver
    Patent number: 7738603
    Abstract: A receiver and method for the same are provided. In the receiver, a decoder may decode an equalized signal to generate symbol decisions and a soft information signal. An equalizer may select boundary levels for non-uniform quantization using a soft information signal delayed by a symbol interval. The equalized signal may be generated from a feedback-filtered signal using the symbol decisions.
    Type: Grant
    Filed: October 28, 2005
    Date of Patent: June 15, 2010
    Assignee: Samsung Electronics Co., Ltd.
    Inventors: Sergey Zhidkov, Hyun-bae Jeon, Taek-won Kwon, Do-han Kim

  • Two-step soft output viterbi algorithm decoder using modified trace back
    Patent number: 6445755
    Abstract: A two-step Viterbi algorithm decoder for tracing the survivor path and the concurrent path and updating a soft decision value, including a soft output Viterbi algorithm state metric unit (SOVA-SMU), which is constructed of registers and multiplexers, instead of a memory for storing survivor information for all states.
