Special Issue on Practical Physical Layer Techniques for 4G Systems & Beyond

The tremendous growth of cellular users over the last decade has called for higher spectral efficiency and better
coverage while maintaining a low power consumption and cost. While early deployments of pre-4G networks support
maximum downlink data rates of 100Mbps, the recent proliferation of multimedia applications and services and
smartphones has led to a growing demand to support data rates that exceed 1Gbps. This has boosted interest in
fundamental as well as applied research on the components and algorithms for 4G systems and beyond.

Several practical challenges in the physical layer need to be addressed in order to support such high data rates.
These challenges include channel sounding, feedback, codebook design for multi-user MIMO systems, multiple
access techniques, noise and interference management, receiver equalization, capacity enhancement, and other
similar problems. Interference alignment techniques are also important in the context of cellular systems, which are
interference limited. This Special Issue welcomes original work from both researchers and practitioners that
explores recent advances in practical approaches to realize multiuser and network MIMO, cognitive radio, co-
operative, and energy-efficient communications.
