Load modulated massive MIMO

2014 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2014
We propose a new hardware architecture for cost-and size-effective implementation of massive MIMO transmitters based on load modulation that is fully compatible with standard receiver architectures. With load modulation, a massive MIMO transmitter can be driven by a single power amplifier operating at constant envelope.

Random phase modulation in load modulated arrays

2017 IEEE 28th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2017
Load modulated arrays (LMAs) are gaining research attention as an attractive transmitter architecture for multiple-input multiple-output (MIMO) systems. A key advantage of LMAs is that they eliminate the need for RF chains at the transmitter (consisting of DACs, mixers, filters) and use only one central power amplifier for any number of antenna ...

Blast Loads for Offshore Modules

Offshore Technology Conference, 1991
ABSTRACT This paper discusses the methods by which the overpressures created by a hydrocarbon explosion within a congested offshore module may be calculated. The nature of the results obtained from numerical simulation are discussed leading to an approach by which a structural loading suitable for use in a linear ...
