Abstract
A new approach to asynchronous multiple access communications is presented. The technique, employing orthogonal convolutional coding and Viterbi decoding, is described and its performance characteristics are derived for the case in which other-user interference is the only source of noise. Results indicate that the technique is quite efficient in terms of the number of users supportable at a specified bit error rate in a given system bandwidth. Furthermore, the results of a design study are described, showing that the technique is a practical one to implement.Keywords
