    Abstract: Method of identification and compensation for inversion of the input bit stream when decoding LDPC codes includes obtaining a code word of the LDPC code from a demodulator output and writing the code word into a buffer memory, decoding the code word, calculating a syndrome for each iteration when decoding, making an analysis of converging the weight of the syndrome, generating an inversion feature for the input bit stream based on this analysis, continuing the decoding, if the inversion feature for the input bit stream does not give evidence of detecting inversion, resetting, if the inversion feature for the input bit stream shows inversion, the LDPC decoder and analysis parameters for the convergence of the weight of the syndrome, reading next code word from the buffer memory, and producing an inversion of this code word, and feeding the word to the decoder input to implement the next decoding operation.

    Abstract: In nonbinary iterative decoding, a data recovery scheme corrects for corrupted or defective data by determining reliability metrics for blocks of decoded nonbinary data. Block or windowed detectors generate block reliability metrics for data blocks (rather than individual bits) of decoded data using soft information from the regular decoding mode or from new iterative decoding iterations performed during defect detection mode. A defect detection system triggers corrective decoding of selected data blocks based on the block reliability metrics, by for example, comparing the block reliability metrics to a threshold or by selecting an adjustable number of the least reliable data blocks.

    Abstract: Coding techniques for a (e.g., OFDM) communication system capable of transmitting data on a number of “transmission channels” at different information bit rates based on the channels' achieved SNR. A base code is used in combination with common or variable puncturing to achieve different coding rates required by the transmission channels. The data (i.e., information bits) for a data transmission is encoded with the base code, and the coded bits for each channel (or group of channels with the similar transmission capabilities) are punctured to achieve the required coding rate. The coded bits may be interleaved (e.g., to combat fading and remove correlation between coded bits in each modulation symbol) prior to puncturing. The unpunctured coded bits are grouped into non-binary symbols and mapped to modulation symbols (e.g., using Gray mapping). The modulation symbol may be “pre-conditioned” and prior to transmission.
