recommendations! Published in 2018 at "IEEE Journal on Selected Areas in Communications"

DOI: 10.1109/jsac.2018.2832832

Abstract: Delay/disruption tolerant networking (DTN) was proposed for reliable data transfer despite frequent link disruptions and long propagation delay that are typical of the deep-space communication environment. DTN communications rely heavily on its core bundle protocol… read more here.

DOI: 10.1109/jsac.2024.3365881

Abstract: This paper studies the mutual information for a general form of orthogonal M-ary frequency-shift keying (MFSK) modulations with non-coherent detection and Doppler frequency uncertainty at the receiver. The signal model includes as particular cases classical… read more here.

DOI: 10.1109/lwc.2019.2916854

Abstract: In space communications, there exist two prominent issues: large Doppler spread and limited pilot resources, which will result in poor performance for a pilot-aided (PA) traditional carrier synchronization mode (TCSM) with serial processing. In view… read more here.

DOI: 10.1109/taes.2022.3170869

Abstract: Bundle protocol (BP) was proposed as the core protocol of delay/disruption-tolerant networking for space. A hybrid reliable transmission mechanism based on integrating “proactive” retransmission and “reactive” retransmission of BP bundles has been presented as a… read more here.
