Abstract: A communication device is configured to encode and/or decode low density parity check (LDPC) coded signals. Such LDPC coded signals are characterized by LDPC matrices having a particular form. An LDPC matrix may be partitioned into a left hand side matrix and the right hand side matrix. The right hand side matrix can be lower triangular such that all of the sub-matrices therein are all-zero-valued sub-matrices (e.g., all of the elements within an all-zero-valued sub-matrix have the value of “0”) except for those sub-matrices located on a main diagonal of the right hand side matrix and another diagonal that is adjacently located to the left of the main diagonal. A device may be configured to employ different LDPC codes having different LDPC matrices for different LDPC coded signals. The different LDPC matrices may be based generally on a common form (e.g., with a right hand side matrix as described above).

Abstract: A communication device is configured to perform processing of one or more bits to generate a modulation symbol sequence based on one or more profiles that specify variable bit loading of bits per symbol over at least some of the modulation symbols of the modulation symbol sequence. The communication device is also configured to perform interleaving of the modulation symbol sequence to generate OFDM symbol(s). Some modulation symbols within the modulation symbol sequence that are separated by an interleaver depth may be transmitted via adjacently located sub-carriers, while other modulation symbols within the modulation sequence that are separated by more than the interleaver depth may also be transmitted via adjacently located sub-carriers. A communication device may be configured to adapt and switch between different operational parameters used for bit loading, interleaving and/or deinterleaving at different times based on any desired considerations.

Abstract: A communication device is configured to perform interleaving of a modulation symbol sequence to generate an OFDM symbol. Some modulation symbols within the modulation symbol sequence that are separated by an interleaver depth may be transmitted via adjacently located sub-carriers, while other modulation symbols within the modulation sequence that are separated by more than the interleaver depth may also be transmitted via adjacently located sub-carriers. First adjacently located sub-carriers transmit first and second modulation symbols that are separated by the interleaver depth within the modulation sequence while second adjacently located sub-carriers transmit third and fourth modulation symbol that are separated by more than the interleaver depth within the modulation sequence. A communication device may be configured to adapt and switch between different operational parameters used for interleaving and/or deinterleaving at different times based on any desired considerations.

Abstract: A demodulator processes a continuous-time signal to generate at a plurality of encoded bits. An inner decoder processes a first subset of bits within the plurality of encoded bits to correct selected ones of the first subset of bits to form a corrected first subset of bits and to generate partially corrected data from the plurality of encoded bits based on the corrected first subset of bits. An outer decoder processes the partially decoded data, to correct selected ones of a second subset of the plurality of encoded bits to form a corrected second subset of bits. A bit combiner generates data estimates by combining the corrected first subset of bits and the corrected second subset of bits.

Abstract: A communication device is configured adaptively to process a receive signal based on noise that may have adversely affected the signal during transition via communication channel. The device may be configured to identify those portions of the signal of the signal that are noise-affected (e.g., noise-affected sub-carriers of an orthogonal frequency division multiplexing (OFDM) signal), or the device may receive information that identifies those portions of the signal that are noise-affected from one or more other devices. The device may be configured to perform the modulation processing of the received signal to generate log-likelihood ratios (LLRs) for use in decoding the signal. Those LLRs associated with noise-affected portions of the signal are handled differently than LLRs associated with portions of the signal that are not noise-affected. The LLRs may be scaled based on signal to noise ratio(s) (SNR(s)) associated with the signal (e.g., based on background noise, burst noise, etc.).
