Abstract

In this paper, we propose an allocation algorithm that minimizes the base station (BS) transmit power of broadcast link OFDMA cellular networks and satisfies the user rate requirements. By minimizing the base station transmitted power, the co-channel cell interference (CCI) can be reduced effectively. To perform the mitigation of the CCI, a fixed amplify and forward relay station (RS) that assists the BS to broadcast data to mobiles in the cell edge region, has been adopted. Numerical results are used to show the improvement of the proposed optimal cooperative scheme compared to the performance of similar scheme without relays.
