Abstract

In this paper, we present a novel and efficient Subcarrire Allocation algorithm with Minimum Data RAte (SAMDRA) constraint for multiuers orthogonal frequency division multiple access (OFDMA) wireless networks. The proposed algorithm attempts to exploit both the time diversity and frequency diversity in the wireless channel. A concept of service expectation is used to indicate how users hope to be served and have their quality of service (QoS) guaranteed. The subcarrier allocation problem is decomposed into two stages. The first stage is to decide which user to be served based on the service expectation and channel quality of users. In the second stage, a sub-carrier is chosen for the current user in order to maxi-mize the average data rate. Numerical results demon-strate a significant improvement in the average date rate under the constraint of minimum data rate guarantee for users.
