Finally, the channel estimation method for MIMO is presented. Using the output 𝒀 of the ICA after phase compensation and ordering, the received signal S, and the channel matrix estimated from the pilot sequence, we can express it as in Equation (8). In this study, the channel coefficients are evaluated based on the Mean Square Error (MSE) of the estimated values of the channel coefficients. Let ℎ_𝑛𝑚 be one element of the channel coefficient matrix and ℎ ̃_𝑛𝑚 be one element of the estimated channel coefficient matrix, the MSE is given by (9).
