主　　题：LEO adaptive array ALOHA packet radio networks 

摘      要：Information integrity is key to successful operations in intricacy environments in the future, especially when strong interferences exist. This paper presents the design of a novel wireless packet network receiver system for Low Earth Orbit （LEO） micro-satellites with adaptive nulling antenna arrays. It uses three types of interference suppression in cascade： namely spread spectrum, adaptive array nulling, and transform domain filtering. This paper proposes a pilot channel-aided method in order to make full advantage of this arrangement, and analyzes its throughput and delay performance using the Markov chain model. Our results show that this method can achieve excellent delay and throughput performance： When the number of array antenna is 8, its throughput increase relative to the standard Slot-ALOHA protocol is 125 96.
