In Figure 8, we show the channel estimates for an environment with 16 UEs and 16 BS antennas, using the deep expansion.
The channel estimation accuracy is evaluated using the mean square error of the channel estimates.
The channel MSE shown in Figure 8 represents the average of all the estimated elements of the channel coefficient matrix 𝑯.
Figure 8 shows that DUICA improves the accuracy of channel estimation compared to the system with only ICA.
It is also confirmed that the accuracy of channel estimation improves as the SNR value increases.
Therefore, it is confirmed that DUICA improves the accuracy of channel estimation and that channel estimation is effective. |
