N2 - The Viterbi detector, based on the Viterbi algorithm used to decode convolutional codes, exhibits improved error performance for intersymbol interference (ISI) channels relative to linear receivers. However, the detector is complex as its storage and processing requirements grow exponentially with channel memory. A truncated-state Viterbi detector assumes the channel memory is less than it really is. An implementation of a truncated-state Viterbi detector on a eight-bit microprocessor is considered. This implementation is tested in the laboratory and experimental results are compared with theory and a digital computer simulation of the communication process. The results give an estimate of the implementation loss that would be introduced in a more practical digital implementation.
