Non-coherent hierarchical cooperation

2010 48th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2010
Hierarchical cooperation is a communication strategy introduced recently by Ozgur et al., where it was shown to significantly outperform standard multi-hop communication in some wireless scenarios. To achieve this gain over multi-hop communication, full availability of channel state information at all the nodes in the network is required. In this paper,

Non-Coherent NOMA With Massive MIMO

IEEE Wireless Communications Letters, 2020
By accommodating overlapping transmissions over non-orthogonal resources, non-orthogonal multiple access (NOMA) integrated with massive multiple-input multiple-output (MIMO) can boost spectral efficiency and obtain vast diversity for wireless multiuser systems.

A Novel Non-Coherent SCMA With Massive MIMO

IEEE Wireless Communications Letters, 2022
—The synergistic amalgamation of sparse code multiple access (SCMA) and multiple-input multiple-output (MIMO) technologies can be exploited for improving spectral efficiency and providing enhanced wireless services to massive users. In this case, however, channel estimation is a burning issue with the increasing number of users and/or antennas.

ODQPSK non-coherent reception

2000 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.00CH37100), 2002
This paper is concerned with a novel high performance non-coherent receiver structure for offset differential QPSK modulation. This structure accepts as input a complex baseband signal sampled at twice the transmission bit rate, evaluates the differential phase of this complex signal and performs simultaneous soft differential decoding, inter-symbol ...

Non-coherent scattering

Journal of Quantitative Spectroscopy and Radiative Transfer, 1973
Abstract The paper is devoted to the consideration of the problems of non-coherent scattering in a spectral line for an arbitrary redistribution law. The representation of the redistribution function r(x′,x) in the form r(χ′,χ) = ∑ k = 1 ∞ A k α k (χ′)α k (χ) is used to study the various mechanisms of line broadening.
