Multi-slot and multi-user joint detection scheme for CRDSA in satellite network
IEICE Communications Express, 2018 : A multi-slot and multi-user detection scheme is presented for the contention resolution diversity slotted ALOHA (CRDSA) in satellite networks. The scheme can effectively resolve the deadlock loop of the collided packets of J users in J slots, and can be

Exploring Core Regular Double Stone Algebras, CRDSA, II. Moving Towards Duality [PDF]
, 2018 This is the second in a series of three notes on an investigation into core regular double Stone algebras, CRDSA, which are meant to be read in order. This note begins our investigation of duality for CRDSA through bi-topological spaces. More succinctly, duality through refinement of a pre- established duality of pairwise Stone spaces and bounded ...

Performance Enhancements for Asynchronous Random Access Protocols over Satellite [PDF]
2011 IEEE International Conference on Communications (ICC), 2011 In this paper, a novel enhancement of the well known ALOHA random access mechanism is presented which largely extends the achievable throughput compared to traditional ALOHA and provides significantly lower packet loss rates. The novel mechanism, called
