Design of multidimensional signal constellations
IEE Proceedings - Communications, 2003An algorithmic technique intended for signal constellation design for an N-dimensional Euclidean signal space is presented. Such signals are used for reliable and efficient digital communications on an additive white Gaussian noise channel. The minimum Euclidean distance between signals and the constellation-constrained capacity are used as performance

2019 11th International Conference on Wireless Communications and Signal Processing (WCSP), 2019
This paper proposes an improved QPSK modulation scheme which is called special QPSK. The key aspect of special QPSK is that the synchronous sequence is hidden in the information bits and does not occupy spectrum resource. In order to implement frame synchronization, correlation acquisition has been considered.

Constellation Design for Memoryless Phase Noise Channels
IEEE Transactions on Wireless Communications, 2014In this paper, we optimize the constellation sets to be used in communication systems affected by phase noise. The main objective is to find the constellation which maximizes the channel mutual information under given power constraints. For any given constellation, the average mutual information (AMI) and the pragmatic average mutual information (PAMI)

Mission Design of the ORBCOMM Constellation
1998ORBCOMM is the first LEO commercial communications satellite to reach orbit and begin service. Offering paging, messaging, and data transfer services, the first two of the thirty-six member constellation were launched in April 1995. Two additional satellites are scheduled for a Taurus launch in late 1997, and subsequent Pegasus XL launches will carry ...

Autonomous interplanetary constellation design
2012According to NASA?s integrated space technology roadmaps, space-based infrastructures are envisioned as necessary ingredients to a sustained effort in continuing space exploration. Whether it be for extra-terrestrial habitats, roving/cargo vehicles, or space tourism, autonomous space networks will provide a vital communications lifeline for both future

Satellite Network Constellation Design
2014Satellite constellation design plays an important role in satellite network robust QoS routing technology. Although robust QoS routing technology should not depend on constellation design, constellation design can affect the system cost, the effective communications of the entire network, and the effective and convenient management of the satellite ...
