Summary on Grant Application Form |

This project is concerned with the design of convolutional decoders employing a new decoding algorithm implemented using new current-mode analogue circuits and subsystems. Convolutional decoders have long been important in applications where very noisy channels are encountered, such as satellite communications. The technique has recently become much more significant with the advent of new application areas such as mobile radio systems of various types and digital magnetic disk recording. Convolutional decoders conventionally employ the Viterbi algorithm (VA), implemented if software or in digital hardware, depending on the requirements and constraints of the application. Our proposed algorithm enables a convolutional decoder to be constructed using analogue components only, which offers the potential for the construction of very small and economical systems. In addition, our circuits and subsystems can be used to improve certain aspects of the performance of existing decoders employing the VA. Our preliminary studies suggest that the proposed new circuits, subsystems and algorithm will exert a considerable influence on the future design of convolutional decoders.
