Abstract: The present invention is directed to data communication systems and techniques thereof. More specifically, embodiments of the present invention provide an FEC encoder that generates parity symbols that are embedded into FEC blocks. An FEC decoder determines whether to perform error correction based on the parity symbols. When performing error correction, the decoder selects a worst symbol from a segment of symbols, and the worst symbol is corrected. There are other embodiments as well.

Abstract: The present invention is directed to data communication systems and methods. More specifically, embodiments of the present invention provide a communication system that removes reflection signals. A digital data stream is processed through both tentative path and the main path. The tentative path uses a first DFE device and a reflection cancellation circuit to generate a correction signal for removing reflection signal from the digital data stream. A second DFE device removes ISI and other noises from the corrected digital data stream. There are other embodiments as well.

Abstract: The present invention relates to data communication systems and methods thereof. More specifically, embodiments of the present invention provide a data transmission method. Data are encoded with staircase encoder, and staircase coded blocks are first interleaved then combined into outer code frames. Code frames additionally include sync words and padding bits. A second interleaving is applied to the bits of the code frames, and Hamming encoding is performed on the output of the second interleaver. Hamming codewords are Gray-mapped to dual-polarized quadrature-amplitude-modulation (DP-QAM) symbols, and a third interleaving of the symbols from a set of successive Hamming codewords is performed. Pilot symbols are inserted periodically into the stream of DP-QAM symbols. There are other embodiments as well.
