A channel in a wireless communication link is often
treated as time invariant over an estimation interval, during
which a least squares estimate of the channel is calculated,
using training symbols.
By a second order Taylor expansion of the channel,
the estimation error, due to time variation,
can be approximated as a bias and an excess error,
which are due to the curvature and linear
change of the channel, respectively.
Approximate expressions for the variance of the estimation
error, in a Rayleigh fading channel, are presented here.
