Abstract: In a method of detecting an error pattern in a codeword transmitted across a noisy communication channel, a codeword is detected. A syndrome is then generated by applying a generator polynomial to the codeword. The generator polynomial is adapted to produce a distinct syndrome set for each of “L” (L>1) different error patterns potentially introduced in the codeword during transmission across the communication channel. A type of an error pattern within the codeword is detected based on the syndrome or a shifted version of the syndrome, and then a start position of the error pattern within the codeword.

Abstract: Digital communication signals that encode information in the phase may be susceptible to phase error from many sources. The invention corrects for carrier and sampling phase errors, as well as additive phase noise. A digital phase locked loop simultaneously tracks the carrier phase error and the sampling phase error, and corrects the signal in the frequency domain. The invention may use the sampling phase error to advance or delay the sampling window used to convert the signal from the time domain to the frequency domain.

Abstract: A method of constructing an effective generator polynomial for error correction by which a unique set of syndromes for each error event is produced is provided. The method includes preparing a set of dominant error events from the intersymbol interference characteristics of media; and generating a codeword from the data using a non-primitive generator polynomial that produces a unique syndrome set which can completely specify each dominant error event.

Abstract: An estimated current phase error is used to control the oscillation frequency of a voltage controlled oscillator used to control the timing of sampling operations performed by an analog to digital converter (ADC). The current phase error is calculated by a recursive computation using a previous phase error in order to eliminate noise effects from the current phase error.

Abstract: Demodulation techniques for a wireless communication system make use of a decision feedback equalization (DFE) technique to mitigate the effects of multipath channel characteristics on receiver performance. The techniques may be particularly useful in the demodulation of complementary code keying (CCK) symbols. A demodulator that performs such techniques may include a time-variant or time-invariant matched filter, a feedback intersymbol interference (ISI) canceller, a transform unit, a phase rotation estimator and corrector, a pattern-dependent bias canceller, and a maximum picker for symbol decisions. The transform unit may include a bank of correlators, or alternatively a fast Walsh transform unit.

Abstract: Techniques are described for detecting error events in codewords detected from data signals transmitted via a communication system. The error events are detected with an error detection code that corresponds to one or more dominant error events for the communication system. The invention develops a class of error detection codes to detect specific error events of known types. In some embodiments, the communication system comprises a recording system. The error detection coding method may be used in conjunction with error correction processing to provide substantial performance gain compared to conventional parity-based post processing methods. For example, the error correction processing may include one or more correlation filters that correspond to the one or more dominant error events for the communication system. A correction module may correct the codeword based on a type of the detected error event and a location of the detected error event in the codeword.
