Abstract

This paper describes a robust error control scheme used for propagation paths especially involving a long time‐frame burst error as in mobile radio communication and its effect on actual data communication channels. This is an adaptive error control scheme based on forward error correction code and composed adaptively of plural coding modes. Here, the BCH code is used as a block code, the diffused code is used as a convolutional code, and 3–5 majority logic is used as a majority voting code. The optimum coding mode is selected automatically according to the status of data transmission channels composed of a radio transmission span and telephone cable transmission lines. Cyclic code is used as an error detection method to evaluate channel status. Under practical transmission circumstances, extremely high throughput efficiency of more than 70 percent is realized for 4800 bit/s data for transmission over the cellular network in Britain. This scheme has been presented at CCITT SG XVII as a standard scheme candidate.
