Resource allocation (RA) for wireless networks is the process of deciding how a set of network resources are used. Among various techniques listed in Multiple Access Scheme, Orthogonal Frequency Division Multiple Accesses (OFDMA) has been chosen as a good strategy to allocate the limited resources by sharing channel. In the other side OFDMA has no intracell interferences because each carrier is assigned exclusively to only one user. The integration of OFDMA scheme to RA show good potential to solve limited bandwidth, improve system performance and high robustness. The main problems occur in resource allocation based OFDMA is how to estimate the channel providing optimum power allocation between different sub channels. Scenarios in wireless systems consist of time, frequency and power resources. Power resource allocation is mainly referred as setting the transmit power. The transmitter’s power determines the wireless link capacity which further influences the throughput of the whole network. 2014 Thesis https://ir.uitm.edu.my/id/eprint/81067/ https://ir.uitm.edu.my/id/eprint/81067/1/81067.pdf text en public masters Universiti Teknologi MARA (UiTM) Faculty of Electrical Engineering Idris, Azlina
