Irregular Repetition Slotted ALOHA with Priority (P-IRSA)
2016 IEEE 83rd Vehicular Technology Conference (VTC Spring), 2016In this paper, a random access with priority protocol named irregular repetition slotted ALOHA with priority (PIRSA) is introduced. By optimizing the packets repetition and using successive interference cancellation (SIC), irregular repetition slotted ALOHA (IRSA) has achieved a high throughput. Contention resolution diversity slotted ALOHA with access

Detecting the Number of Active Users in IRSA Access Protocols
2018 IEEE 29th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2018We develop a maximum a posteriori detector for the number of unrecovered users in coded random access systems based on the irregular repeat slotted Aloha (IRSA) protocol, where each user transmits in random slots multiple packet replicas whose number (known as the user degree) is drawn according to a given probability mass function and where successive

AUV IRSAS for submarine hydrothermal deposits exploration
2016 IEEE/OES Autonomous Underwater Vehicles (AUV), 2016Small AUV “IK-A” equipped with IRSAS was developed for submarine hydrothermal deposits exploration. Observed IRSAS data could acquire the back scatter image and bathymetry. One of the features of the seafloor hydrothermal deposits is the chimney and the mound-like terrain. Back scatter image can distinguish these terrain and other terrains.

Throughput Analysis of PDMA/IRSA under Practical Channel Estimation
2019 IEEE 20th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2019Pattern division multiple access (PDMA) and irregular repetition slotted aloha (IRSA) are non-orthogonal multiple access (NOMA) protocols wherein packets are repeated across different resource elements. In this paper, first, the throughput of PDMA/IRSA is analyzed when common pilots are employed across users to facilitate channel estimation at the base

Feedback-aided irregular repetition slotted ALOHA (F-IRSA)
2017 9th International Conference on Wireless Communications and Signal Processing (WCSP), 2017In this paper, we propose a feedback-aided irregular repetition slotted ALOHA (F-IRSA) protocol which depends on the distance between the received packet and the set of packets already recovered at the receiver. We employ feedback messages to terminate the user retransmission process, and use successive interference cancellation (SIC) for packet ...
