Fig. 8From: A low-complexity channel training method for efficient SVD beamforming over MIMO channelsBER comparison with \(L_1 = L_2 = 4\), \(L_1 = L_2 = 32\) and \(L_1 = L_2 = 128\) symbols for channel estimation, and \(m=1\) (RCPA) and \(m=4\) iterations of the PIA using a \(4 \times 4\) MIMO array. They are compared to the theoretical SVD-BF BER with ideal channel knowledgeBack to article page
