A multi-carrier modulation communications system and method (100) for
providing
channel estimation that uses a transmitter for inserting pilot symbols in a digital
multi-carrier modulated radio frequency (RF) signal and a receiver for receiving
the pilot symbols in multi-carrier modulation RF signal. In order to provide channel
estimation the receiver detects (101) channel power gains from a plurality
of designated pilot symbols and calculates (103) both a speed parameter
(S) and a multi-path parameter (M) for the channel receiving the pilot symbols.
A channel model is then defined (105) based upon the speed parameter and
multi-path parameter value and a predefined set of pilot coefficients is chosen
(107) that substantially matches the channel model. The resulting set of
pilot coefficients is then utilized (109) for optimizing pilot symbol interpolation.
