Abstract: Making full use of advanced physical layer technique like orthogonal frequency multiply access (OFDMA) and distributed antenna. Compared with the distributed radio resource scheduling algorithm, a tri-angle cellular architecture with distributed antennas was proposed, the related centra lized layer could descend interference down to 13.4dB
