简介
In the future, high capacity downlink would be required in cellular system with quality of service provisioning. The quality of services (QoS) means acceptable data transfer rate, signal to noise ratio (SNR), and bit error rate (BER). It can be achieved by management of resources in orthogonal frequency division multiple access (OFDMA) system. The main issue in OFDMA systems is allocation of sub-carriers and power among different types of users. In this paper, an algorithm is proposed for heterogeneous users in OFDMA system. Two different types of users are considered on the basis of required quality of services that is sensitive user (SU) and general user (GU). While the priority is given to the sensitive users, some resources are also allocated to general users to keep the system fair. The complexity of algorithm is also a major issue and it can be reduced by allocation of subcarrier and power sequentially. The …
