信道估计,we will assume that the receiver knows your name, i.e., it knows s (and of course

x). Based on this knowledge, the receiver will estimate h using the MVU and MMSE method

(for the latter it is also assumed that the variance of the noise σ2 is known at the receiver).-Channel Estimation:we will assume that the receiver knows your name, i.e., it knows s (and of course
