IEEE Wireless Communications Letters, 2022
In this letter, we study the integrated satellite-terrestrial network where users can access the core network by the backhaul links via both multi-layer satellites in the space and terrestrial access points on the ground.

Regional CubeSat Constellation Design to Monitor Hurricanes
IEEE Transactions on Geoscience and Remote Sensing, 2022State-of-the-art weather forecasting systems depend on a variety of data collected by airborne, orbiting, and ground sensors. Regional CubeSat constellations have the potential to improve hurricane forecasting by collecting sensor data over data-starved ...

The Skybridge Constellation Design
17th AIAA International Communications Satellite Systems Conference and Exhibit, 1998The SkyBridge space segment, based upon Low Earth Orbit satellites, had to face a challenge: though using the same frequency band as various geostationary systems in order to profit by well-proven and cost-efficient techniques — i.e. Ku Band -, SkyBridge satellites must not in any way interfere with geostationary satellites.

Joint Constellation Design and Multiuser Detection for Grant-Free NOMA
IEEE Transactions on Wireless Communications, 2022As a promising solution for massive machine-type communication, grant-free non-orthogonal multiple access (GF-NOMA) has received considerable attention in recent years. However, the multidimensional constellation design (MCD) and multiuser detection (MUD)

Proceedings of the 14th Participatory Design Conference: Short Papers, Interactive Exhibitions, Workshops - Volume 2, 2016
Sustaining participation in design is difficult, especially in neighborhoods that seek change consistent with their cultural values. Participatory Design offers several approaches (e.g. infrastructuring) that help to balance the sensibilities of urban planning with the immediacies of design.

Constellation Design for Noncoherent Massive SIMO Systems in URLLC Applications
IEEE Transactions on Communications, 2021In this paper, we concern the uplink of a massive single-input multiple-output enabled ultra-reliable low-latency communication system, in which a single-antenna transmitter aims to timely and reliably send data to a receiver equipped with a large number
