ABSTRAKT

This paper presents a new noise immunity coding technique based on the properties of triple correlation and bispectrum widely used in digital signal and image processing. Encoding and decoding algorithms are described and tested for digital radio telecommunication system with binary frequency shift keying. Probability of errorless decoding has been investigated by computer simulation of transmission and reception of a binary-coded test message in telecommunication system with radio channel disturbed by both the additive white Gaussian noise (AWGN) and mixture of AWGN and impulsive noise. Computer simulation results obtained for varying signal-to-noise ratios smaller than unity at the demodulator input demonstrate considerable improvement of noise immunity of the technique proposed in comparison to the conventional redundant linear block coding technique.
