Figure 5From: Water-filling for full-duplex multiple-hop MIMO relay systemThe effect of outdated CSI when SNR = 20 dB and the term f D Ï„ is changed. The end-to-end channel capacity of the outdated CSI system is described in the high-SNR region. The end-to-end channel capacity in the high-SNR region decreases more quickly than that in the low-SNR region.Back to article page
