Performance analysis of frequency-hopped packet radio networks with side information generated from test symbols

This paper is concerned with the performance analysis of frequency-hopped packet radio networks with erasure only decoding. Reliable side information are generated by inserting a special group of test symbols in each dwell. Although the primary use of test symbols is to insure reliable side information, it has the additional potential benefit of making data symbols capable of discriminating partial overlaps. Closed form expressions for packet capture probabilities are derived for random and one-coincidence hopping patterns. Numerical results indicate that, increasing the number of test symbols leads to a significant improvement in the throughput at high traffic levels.
