PERFORMANCE ANALYSIS OF FREQUENCY-HOPPED SPREAD-SPECTRUM PACKET RADIONETWORKS .1. SLOTTED MULTIPLE-ACCESS

This paper is concerned with the performance analysis of slotted frequ ency-hopped packet radio networks with Reed-Solomon forward error cont rol coding. Both random and one coincidence frequency hopping patterns are considered. A new concept of the pair-wise hit patterns and the e ffective multiple-access interference are introduced. The joint probab ility generating functions of these interference vectors are determine d for both synchronous and asynchronous hopping. Closed form expressio ns for packet capture probabilities and throughput are derived in term s of these joint generating functions. Finally a direct proof is given that hits in different symbols are asymptotically independent.
