Abstract :
Orthogonal Frequency Division Multiple Access (OFDMA) allows multiuser to make use of the same bandwidth as the single user OFDM for data transmission. This paper considers resource allocation algorithm which supports the user Quality of Service (QoS) with Multiuser OFDM cellular system. In this paper, we discuss how to achieve QoS without wasting subcarriers after subcarrier allocation. A proposed method assigns subcarriers from users not satisfying QoS to users who can contribute to system capacity.
