Abstract: A syndrome assisted iterative decoder (173) uses iterative processing to decode an input sequence. A syndrome-assisted decoder (216), which may operate independently of a soft-output decoder, provides a stopping algorithm for the soft output decoder (240). When the syndromes s0 and s1 generated for sequence v0 and v1, respectively, both equal 0, the soft output decoder is finished decoding the sequence of data. Additionally, the syndrome-assisted decoder can generate a modified error trellis used by the soft output decoder whereby the soft-output decoder operates on a simplified trellis providing improved decoder performance.

Abstract: A switchable-output encoder for encoding an input data sequence into an error protection encoded output sequence is switchable between two encoding modes. The encoder modes comprise a relatively complex mode suitable for a relatively high noise level channel and a relatively simple mode suitable for a relatively low noise level channel. A corresponding decoder is also discussed.

The decoder and calculator are interconnected, and jointly converge on an output which is an estimate of a transmitted sequence.

Abstract: A coset analyzer is used for analyzing time-varying error correction codes in data communications. The time-varying error correction code has cosets, and each coset has a coset leader and a syndrome. The analyzer comprises a coset representation unit for representing a coset of the code as a time-varying error trellis and an error trellis searcher for searching the error trellis. Each member of the coset corresponds to a path through the error trellis. A lossless data sequence compressor and decompressor are also discussed.

Abstract: A method of discriminating between equally probable trellis paths surviving in a trellis decoder to select a single output path. The method comprises: windowing over the trellis decoder to view said surviving paths in successive windows, identifying a predetermined feature in the paths as they appear in the successive windows, and eliminating surviving paths having the predetermined feature to leave a single surviving path to form the single output path.

Abstract: Soft output decoding of signals represented by a trellis of block length N divided into windows includes a step of decoding a forward recursion to a location that is I sections from the beginning of the window. An optimum state is detected at the end of the forward recursion. A backward recursion is performed from the determined state at the end of the window back to the beginning of the window to define a set of known backward recursion state metrics. Soft outputs are calculated during the backward recursion using the stored forward recursion state metrics, the backward recursion state metrics, and branch metrics at each state.

Abstract: A soft-decision decoder computes a maximum likelihood estimated transmitted code from a demodulated received signal with less complexity compared to a conventional Viterbi soft-decision decoder. A symbol-by-symbol detector determines a hard-decision vector from a demodulated received signal vector. A syndrome calculator multiplies the hard-decision vector by a scalar parity check matrix to calculate a syndrome vector. A syndrome modifier examines the syndrome vector for predetermined syndrome patterns corresponding to isolated errors in the hard-decision vector. Syndrome patterns are removed from the syndrome vector to create a modified syndrome vector, and the corresponding error in the hard-decision vector is recorded in an estimated error vector. A syndrome-based decoder uses the modified syndrome vector to create a simplified error trellis to produce a remaining error vector.

Abstract: A syndrome-based channel quality or message structure determiner (160) uses syndrome vectors to estimate the quality of a received signal in a variable message structure communication system. A digital signal from analog-to-digital converter (150) is separated into multiple branching paths, one for each potential message structure type. In a single path, a digital demodulator (221) demodulates the digital signal to produce a demodulated received signal. A deinterleaver (222) deinterleaves the demodulated received signal, and a symbol-by-symbol detector (2231) hard-decision detects the deinterleaved signal. For each hard-decision vector, at least one syndrome calculator (2241) calculates a syndrome vector. The syndrome vector is analyzed by a syndrome error estimator (2251) having an associated syndrome pattern memory (2271). A comparator (260) analyzes error counter totals from each syndrome error estimator.
