Abstract Background/Objectives: Proficient usage of available spectrum and energy are
playing an essential role in case of wire communication as well as wireless Communications …

Four schemes for binary solutions are proposed in this work to solve the resource allocation
problem in an OFDMA system. The binary solution is sought at the early stage before …

In recent decades, due to limitation of radio spectrum and increasing users in wireless
networks, spectral efficiency has been a considerable issue in literatures. In addition, energy …

In wireless communications, the demand for wireless throughout and communication
reliability as well as the user density will always increase. In this regard, one of the important …

In this study, the energy-efficiency (EE) problem is investigated for downlink Orthogonal
Frequency Division Multiple Access (OFDMA) cellular networks. The EE maximization …

In this paper, a new energy efficient resource allocation is designed to maximize the system
throughput per unit-energy over frequency selective channels in OFDMA downlink …

Orthogonal frequency division multiple access (OFDMA) is a popular and widely accepted
multiple access technique to provide high data rate services in a mobile environment in the …

Energy has newly become a scarcer resource for the wireless networks, like spectrum. To
utilise the limited resources efficiently and fairly in the downlink OFDMA systems, a novel …

A resource Allocation Problem for spectrum sharing in wireless communication system.
Using multiinput multi-output orthogonal frequency division multiple (MIMO-OFDM) is a very …

ABSTRACT OFDMA is the access scheme used in the third and fourth generation wireless
cellular networks. Proper allocation of bandwidth and power is essential for ensuring the …
