The introduction of wavelength division multiplexing (WDM) has triggered a tremendous capacity growth in submarine systems, both by the increase of the number of WDM channels and by the increase of

In this paper, we derive a deterministic equivalent of the Shannon-transform of certain type of large unitary random matrices.

The effects of using adaptive antenna arrays in third generation CDMA wireless systems are analyzed through simulation studies.

A promising multiple access scheme, which is called nonorthogonal coded access (NOCA), has been proposed for the fifth generation wireless communication systems to achieve higher service quality wi

The contention-based (CB) transmission is a promising solution for small data packets transmission in 5G uplink.

There has been a lot of recent interest in the potential of inter-base station cooperation techniques to manage excessive out-of-cell interference in evolving cellular networks.

In earlier work, we proposed a novel approach towards lifting the limits imposed by cochannel interference on the uplink spectral efficiency of a cellular network, viz., coordinating each base stat

The millimeter wave spectra at 71-76GHz (70GHz) and 81-86GHz (80GHz) have the potential to endow fifthgeneration new radio (5G-NR) with mobile connectivity at gigabit rates.

A Large Scale Antenna System (LSAS) entails a large number (tens or hundreds) of base station antennas serving a much smaller number of terminals, with large gains in spectral efficiency and energy

In this paper, a two-tier UMTS network is considered where a large number of randomly deployed Wideband Code Division Multiple Access (WCDMA) femtocells are laid under macrocells where the spectrum
