In this paper, we propose a channel estimation method which uses piecewise linear interpolation with wavelet de-noising to reduce additive white Gaussian noise (AWGN) and intercarrier interference (ICI) for orthogonal frequency division multiplexing (OFDM) mobile communication systems. The performance including mean squared error (MSE) and bit error rate (BER) of the proposed channel estimator is...
In this paper, we study channel estimation methods with various curve fitting techniques for mobile WiMAX system and find that they cannot support high mobility sufficiently. We also propose a channel estimation method which is based on piecewise linear estimation to overcome the problem of high mobility. The performances including mean squared error (MSE) and bit error rate (BER) are compared and...
