Abstract
Opportunistic beamforming (OB) has been investigated in the 5th generation (5G) network to jointly maximize the sum rate of the secondary network and minimize the interference induced to the primary users. In this paper, we consider the cognitive radio context and we investigate the problem of SINR (signal to interference plus noise ratio) quantization in secondary network. Based on OB, we propose a suitable quantization scheme that minimizes the secondary system throughput loss due to the quantization. Via theoretical analysis and Matlab simulations, we demonstrate that our proposed algorithm attains maximum sum rate and outperforms others schemes proposed in the literature.
