The advent and continued growth of large data centers has led to much interest in switch architectures that can economically meet the high capacities needed for interconnecting the thousands of ser
String complexity is defined as the cardinality of a set of all distinct words (factors) of a given string.
This paper investigates the joint subcarrier and power allocation problem for the downlink of a multi-carrier non-orthogonal multiple access (MC-NOMA) system.
Non-orthogonal multiple access (NOMA) is a promising technology to increase the spectral efficiency and enable massive connectivity in 5G and future wireless networks.
In this paper, we consider the joint subchannel and power allocation problem in both the uplink and the downlink for two-tier networks comprising spectrum-sharing macrocells and femtocells.
The authors report on the existence and interaction of the ground state (GS) and excited state (ES) emission in continuous wave (CW) and large signal pulsed operation at three temperatures (20degC,
In time-varying frequency selective channels, to obtain high-rate joint time-frequency diversity, linear dispersion coded orthogonal frequency division multiplexing (LDC-OFDM), has recently been pr
Beamforming problem is studied in wireless networks where both transmitters and receivers have linear adaptive antenna arrays.
A dense deployment of on-grid small cell base stations (SBSs) in a heterogeneous cellular network (HCN) results in large power consumption which can be reduced by utilizing harvested energy from sc
In recent years, a number of double-sideband suppressed-carrier linear-modulation techniques have seen increasing application to the efficient transmission of digital d a t a over band-limited chan
