The Radio Channel Estimation in this paper is related to the procedure of evaluating the system function of the user channels. These evaluations are assisted by the Zadoff-Chu pilot sequences that are assigned to users. A linear Bayes estimator estimates the instantaneous channel state by minimizing its risk, where the cost function is the Mean-Squared Error (MSE). The estimator induces an estimation error that reaches its minimum value among all linear/affine estimators once the Bayes risk is minimized. The quality of channel estimation is described by the Normalized Minimum Mean-Squared Errors (NMSEs).
