Abstract
The performance of channel estimation in OFDM
systems significantly depends on the pilot signal, which is
usually scattered in the time and frequency domains. For a
given pilot density, we analytically design the optimum pilot
pattern that minimizes the mean square error of the channel
estimate obtained with the use of general interpolators. The
analytic results are verified by computer simulation.
