Estimator robustness of EQ-Net (L), and the similarly performing NN-Det (P) under imperfect CSI for \(2\times 2\), 64-QAM, i.i.d. Rayleigh fading, and LDPC-coded with size (324, 648). The plot shows the coded block error rate at SNR=17.3 dB as a function of the CSI error. The two horizontal lines show the average end-to-end performance of the two algorithms with ideal CSI knowledge at the same SNR value
