Summary:
An adaptive pilot-symbol assignment scheme is proposed for interpolation-based channel estimation in wireless OFDM communication systems. The channel transfer functions of data tones are interpolated by the piecewise-linear and the second-order polynomial interpolation methods due to their inherent simplicity. Simulations are conducted to demonstrate system performance and bandwidth (BW) superiority. A comparative evaluation of the proposed dynamic pilot scheme with conventional fixed pilot-symbol channel estimation schemes is performed as well.
