By using the linear minimum mean square error (LMMSE) estimation algorithm, the destination first estimates the overall channels based on the pilot symbol inherent in frequency-shift keying (FSK) transmission.
Using the linear minimum mean square error (LMMSE) estimator [27] and assuming that all the channel responses are available at the FC, the estimation of s is (check {s} = mathbf {C}_{s mathbf {y}} mathbf {C}^{-1}_{mathbf {y} mathbf {y}}, mathbf {y}), where C s y is the covariance between s and y and C y y is the covariance of y.
In [1], by using the linear minimum-mean-square-error (LMMSE) combiner to optimally combine frequency offset estimators based on single time slot pilot samples from a received time-domain OFDM block, they successfully circumvent the multiple solution difficulty and meanwhile achieve very satisfactory joint estimation performance with wide tracking range (up to half the subcarrier spacing).
