Fig. 8From: A new blind algorithm for channel estimation in OFDM-based amplify-and-forward two-way relay networksComparison of the normalized MSE for CP-OFDM and ZP-OFDM systems for K=500. We compare the proposed algorithm for CP-OFDM and ZP-OFDM systems. The solid curves and the dashed curves represent the MSEs for CP-OFDM and ZP-OFDM, respectively. The number of received blocks is K=500Back to article page
