Hybrid Analog and Digital Precoding: From Practical RF System Models to Information Theoretic Bounds
Vijay Venkateswaran, Rajet Krishnan
Hybrid analog-digital precoding is a key millimeter wave access technology, where an antenna array with reduced number of radio frequency (RF) chains is used with an RF precoding m…
Diversity Pulse Shaped Transmission in Ultra-Dense Small Cell Networks
Amir H. Jafari, Vijay Venkateswaran, David Lopez-Perez +1
In ultra-dense small cell networks, spatial multiplexing gain is a challenge because of the different propagation conditions. The channels associated with different transmitreceive…
Pulse Shaping Diversity to Enhance Throughput in Ultra-Dense Small Cell Networks
Amir H. Jafari, Vijay Venkateswaran, David Lopez-Perez +1
Spatial multiplexing (SM) gains in multiple input multiple output (MIMO) cellular networks are limited when used in combination with ultra-dense small cell networks. This limitatio…
Hybrid Analog-Digital Precoding Revisited under Realistic RF Modeling
Adrian Garcia-Rodriguez, Vijay Venkateswaran, Pawel Rulikowski +1
In this paper we revisit hybrid analog-digital precoding systems with emphasis on their modelling and radio-frequency (RF) losses, to realistically evaluate their benefits in 5G sy…
Hybrid RF and Digital Beamformer for Cellular Networks: Algorithms, Microwave Architectures and Measurements
Vijay Venkateswaran, Florian Pivit, Lei Guan
Modern wireless communication networks, particularly cellular networks utilize multiple antennas to improve the capacity and signal coverage. In these systems, typically an active…
