An integrated error correction and detection system for digital audio broadcasting

IEEE Transactions on Broadcasting, 2000

Hybrid in-band on-channel digital audio broadcasting systems deliver digital audio signals in such a way that is backward compatible with existing analog FM transmission. We present a channel error correction and detection system that is well-suited for use with audio source coders, such as the so-called perceptual audio coder (PAC), that have error concealment/mitigation capabilities. Such error mitigation is quite ...

Error burst detection with high-rate convolutional codes

Proceedings of 1995 IEEE International Symposium on Information Theory, 1995

One crucial requirement for the use of convolutional codes in (only) error detection is low decoding complexity. We show that for this specific application the decoding complexity of convolutional codes is practically equal to the coding complexity, which is very small. Thus, the encoder/decoder can be implemented directly in hardware, or use efficient software decoding techniques like those used for ...


Arithmetic coding-based continuous error detection for efficient ARQ-based image transmission

We propose a new "continuous" error detection scheme using arithmetic coding that provides a novel tradeoff between the amount of ...

  • An integrated error correction and detection system for digital audio broadcasting

    Hybrid in-band on-channel digital audio broadcasting systems deliver digital audio signals in such a way that is backward compatible with existing analog FM transmission. We present a channel error correction and detection system that is well-suited for use with audio source coders, such as the so-called perceptual audio coder (PAC), that have error concealment/mitigation capabilities. Such error mitigation is quite beneficial for high quality audio signals. The proposed system involves an outer cyclic redundancy check (CRC) code that is concatenated with an inner convolutional code. The outer CRC code is used for error detection, providing flags to trigger the error mitigation routines of the audio decoder. The inner convolutional code consists of so- called complementary punctured-pair convolutional codes, which are specifically tailored to combat the unique adjacent channel interference characteristics of the FM band. We introduce a novel decoding method based on the so-called list Viterbi algorithm (LVA). This LVA-based decoding method, which may be viewed as a type of joint or integrated error correction and detection, exploits the concatenated structure of the channel code to provide enhanced decoding performance relative to decoding methods based on the conventional Viterbi algorithm (VA). We also present results of informal listening tests and other simulations on the Gaussian channel. These results include the preferred length of the outer CRC code for 96-kb/s audio coding and demonstrate that LVA-based decoding can significantly reduce the error flag rate relative to conventional VA-based decoding, resulting in dramatically improved decoded audio quality. Finally, we propose a number of methods for screening undetected errors in the audio domain.

  • Enhancement of turbo codes using cyclic redundancy check with interleaver optimisation

    A method is presented where a parallel concatenated convolutional code is preceded with a short cyclic redundancy check (CRC) without code rate loss. Parity bits are punctured and their place taken by the CRC. Results are given for the weight spectrum of an optimised code, rate 2/3, codeword length, n=1014 in comparison with an optimised, nonCRC code using the same rate and codeword length. Frame error rate performance achieved is within 0.36dB of the sphere packing bound constrained for binary transmission.

  • Error burst detection with high-rate convolutional codes

    One crucial requirement for the use of convolutional codes in (only) error detection is low decoding complexity. We show that for this specific application the decoding complexity of convolutional codes is practically equal to the coding complexity, which is very small. Thus, the encoder/decoder can be implemented directly in hardware, or use efficient software decoding techniques like those used for cyclic redundancy check (CRC) error detection codes. Different encoder/decoder implementations are considered. By studying the properties of high-rate convolutional codes for the purpose of error detection, we show their potential advantages over block codes. In addition, this study gives a deeper view of CRC codes-which happen to be a special case in a class of codes that we call unit-rate convolutional codes. Thus, for the extension of CRCs we can employ techniques used for convolutional codes, like the use of unit-memory or cyclic time-varying codes. Certain general error detection capabilities of the convolutional codes are derived.

  • Arithmetic coding-based continuous error detection for efficient ARQ-based image transmission

    Block cyclic redundancy check (CRC) codes are typically used to perform error detection in automatic repeat request (ARQ) protocols for data communications. Although efficient, CRCs can detect errors only after an entire block of data has been received and processed. We propose a new "continuous" error detection scheme using arithmetic coding that provides a novel tradeoff between the amount of added redundancy and the amount of time needed to detect an error once it occurs. This method of error detection, first introduced by Bell, Witten, and Cleary (1990), is achieved through the use of an arithmetic codec, and has the attractive feature that it can be combined physically with arithmetic source coding, which is widely used in state of-the-art image coders. We analytically optimize the tradeoff between added redundancy and error-detection time, achieving significant gains in bit rate throughput over conventional ARQ schemes for binary symmetric channel models for all probabilities of error.

  • An exact evaluation of the probability of undetected error for certain shortened binary CRC codes

    The authors give a computationally efficient algorithm for computing the probability of undetected error for a class of cyclic codes whose generator polynomial is equal to (x+1) times a primitive irreducible polynomial. This class contains three CRC (cyclic redundancy check) codes that have been adopted as international standards. The algorithm was used to compute the performance of a number of codes at various shortened block lengths, often with surprising results. It is suggested that, when dealing with shortened block lengths, one should choose a primitive polynomial with many rather than few nonzero coefficients in order to produce a good code.<<ETX>>

  • Joint source-channel coding using finite state integer arithmetic codes

    Inserting redundancy to arithmetic codes is a common strategy to add error detection capability to this well-known family of source codes. By using this strategy error correction is possible through some decoding algorithms such as Viterbi decoder. In this paper a system has proposed that uses finite state integer arithmetic codes (FSAC) as a joint source-channel code in combination with a cyclic redundancy check (CRC) and a List Viterbi decoder. The proposed scheme has shown better performance than previous ones.

  • On the better protection of short-frame turbo codes

    Protecting short data frames by turbo coding is a challenging task because of the small interleaver size and the need for transmission efficiency. In this letter, turbo-decoding-metrics aided short cyclic redundancy check codes are applied to novel tailbiting encoded trellis codes with a twofold purpose: to stop the iterative decoding processes to achieve low-power design and to reduce fractional coding-rate loss. Significant coding gains can be achieved by actually increasing the transmission rate with a negligible increase in power consumption. Performance improvement is demonstrated over additive white Gaussian noise channels. The savings is up to 21.4% for the transmission throughput and 21.5% for the energy consumption of the turbo decoder when frame size 49 is used.

  • Cyclic redundancy check code based high-rate error-detection code for perpendicular recording

    We present a particular generator polynomial for a cyclic redundancy check (CRC) code that can be used to detect all dominant error events in perpendicular recording over a broad range of densities. This polynomial is also effective in detecting error events that occur at codeword boundaries. The bit-error-rate and the sector-error-rate performances are validated that result from the use of the corresponding CRC code in conjunction with the well-known post-Viterbi error correction method.
