Energy harvesting with the optimum power consumption and packet scheduling increase the lifetime and sustainability of the wireless sensor networks (WSNs) leading to green communications. Optimal packet scheduling solutions available for 2-user multiple-access channel (MAC) systems with energy harvesting transmitters do not consider the common data observed when collected sensor data is spatial...

Inter-cell Co-Channel Interference (ICCI) is a severe problem suffered by cell-edge users in multi-cell OFDMA system, an adaptive interference coordination (AIC) algorithm based on Iterative Water-Filling (IWF) algorithm for multi-cell is proposed. Cell-edge users and cell-center users have different priorities. The resource allocated to cell-edge users is adjusted after each convergence. The c...

In distributed detection systems with wireless sensor networks, communication between sensors and a fusion center is not perfect due to interference and limited communication power of the sensors to combat noise. The problem of optimizing detection performance with imperfect communication between the sensors and the fusion center over wireless channels brings a new challenge to distributed dete...

MIMO systems are used in wireless communications for enhancement of capacity. The number of transmit and receive antennas effect the tradeoff between performance gain and that of multiplexing gain. In this paper we are considering the study of Rayleigh fading affecting the capacity of MIMO channel by mat lab simulation. The Singular Value Decomposition (SVD) has been used to explore further ins...

This paper considers the multiple input multiple output (MIMO) iterative water-filling algorithm (IWFA) for the coexistence of multiple broadcast networks distributing only common information. In the first part of the paper, we propose a power allocation for a MIMO broadcast network using parallel sub-channels and distributing only common information either to maximize the common rate subject t...

Multiple Input and Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) system have the potential to achieve very high capacity depending on the propagation environment. The objective of this paper resource allocation on LTE using is the adaptive resource allocation in MIMOOFDM system using the water filling algorithm. Water filling solution is implemented for allocating...

—This paper considers an OFDMA-based cooperative cognitive radio network where the secondary users (SUs) act as the relay of the primary users (PUs) while guaranteeing the quality of service (QoS) of the PUs. In return, the SUs access the spectrum licensed to PUs in both time and frequency without impacting the communication of the PUs. A joint resource allocation problem is formulated to maxi...

A resource Allocation Problem for spectrum sharing in wireless communication system. Using multiinput multi-output orthogonal frequency division multiple ( MIMO-OFDM) is a very promising technology for enhancing the flexibility and efficiency of cellular and future communication systems. A joint optimization problem for resource allocation is solved by a combine scheme of multiple-input multipl...
