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