What is MMSE channel estimation?

The minimum mean-square error (MMSE) channel estimation has well performance but higher complexity than least-square (LS) channel estimation, specially it requires the channel statistical properties including the channel autocorrelation matrix and the noise variance.

Is MMSE unbiased?

The LMMSE estimator is conditionally biased towards the prior mean which is 0.

What is MMSE in wireless communication?

Multimedia Messaging Service Environment, the servers in a mobile telephony network required for Multimedia Messaging Service messaging.

How is MMSE calculated?

The MSE of the linear MMSE is given by E[(X−XL)2]=E[˜X2]=(1−ρ2)Var(X).
