Figure 4From: A robust beamformer design for underlay cognitive radio networks using worst case optimizationCDF of the received SINR at a secondary RX. Empirical CDF of the received SINR at second secondary RX for different values of ξ. A network with parameters n t = 4,N = 2 and K = 2 is considered. The empirical CDF is calculated over different channel errors for a fixed estimated channel realization.Back to article page
