Abstract :
In this paper, a best response (BR) based iterative power control algorithm is proposed, which could maximize the total throughput of CN. Our proposed joint beamforming and power control algorithm is implemented by the alternate iteration of MMSE-DFE beamforming and BR based power control, we note it as MMSE-BR. Compared with ZF-CML, MMSE-BR could achieve the optimal throughput performance under any interference situation, and does not limit to the number of CU, so is much more robust and practical.
