An Efficient Resource Allocation in MIMO-OFDMA Networks
Journal Title: The International Journal of Technological Exploration and Learning - Year 2013, Vol 2, Issue 5
Abstract
Most of the future wireless communication system applications are purely multimedia applications with the different Quality of Services (QoS) and these systems are required to support a variety of data rate for communication services to its end users, such as video streaming and cloud based services.. Therefore for efficiently providing a proper communication among all these wireless communication systems an attractive multiple access scheme is required, which are possible by using OFDMA scheme (Orthogonal Frequency Division Multiple Access). The main objective behind the use of OFDMA is it builds OFDM (Orthogonal Frequency Division Multiplexing) links, which are very immune to inter-symbol interference and very sensitive to frequency selective fading. In this paper, we discusses about the problems of OFDMA system regarding with resource allocation like power allocation, data rate, allocation of active communication links (antenna allocation), and provides a novel solution for all these problems. In this paper considered problem consists of power consumption of all circuit element (circuit power consumption), CSIT (Imperfect channel state information at the transmitter), and different quality of services like data rate and a maximum tolerable channel outage probability etc.
