dc.description.abstractThe performance of channel estimation can be
improved by employing a channel estimation filter (CEF) that
can adjust its bandwidth in response to the channel condition.
For coherent OFDM receiver, we consider the use of twodimensional
(2-D) moving average (MA) FIR filter with a linear
interpolation filter as the CEF that can provide good
performance without requiring large implementation
complexity. The optimum tap size of 2-D MA FIR CEF is
analytically determined in terms of the pilot spacing, the
channel spectrum and pilot signal to interference power ratio.
The performance of the proposed channel estimator is
evaluated by computer simulation.
