摘要： A receiver apparatus can identify a plurality of patterns corresponding to scrambled synchronization bytes of a transport stream in a number of successive signal frames containing FEC code blocks, determine a pattern distribution into which most of the patterns identified in the successive signal frames map, and generate a synchronization signal locked to a distribution of the FEC code blocks associated with the pattern distribution. With this synchronization signal, FEC code blocks can be timely handled in a reliable manner through a FEC decoder, making the receiver apparatus more efficient and robust. In other embodiments, methods of handling FEC code blocks in a receiver apparatus are also described.

摘要： A tap/group-revivable decision feedback equalizing method and equalizer using the same is disclosed. The equalizer includes a feed-forward filter and a feedback filter each with a plurality of taps divided in groups. The tap/group-revivable decision equalizing method includes training all the taps to generate their tap coefficients, and selecting all the taps of any of the groups with a tap coefficient greater than a predetermined value and selecting a number of taps of any of the groups without a tap coefficient greater than the predetermined value, but with a neighboring group with a tap coefficient greater than the predetermined value are selected, and having the selected taps utilized for equalization.

摘要： A receiver apparatus comprises a LDPC decoder that can apply an accelerated belief propagation method for iteratively decoding each code block. When the number of iterations reaches a certain threshold value, the accelerated belief propagation method can adjust the initial condition used in each iteration. The initial condition is adjusted so as to enhance the likelihood of convergence in the iterative method. As a result, performance of the decoder and receiver apparatus can be improved.
