PILOT SEQUENCES ASSISTED RADIO CHANNEL ESTIMATION
Abstract
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).
