Nonlinear Channel Estimation for OFDM System by Wavelet Transform Based Weighted TSVR
An efficient nonlinear channel estimation method for pilot-aided orthogonal frequency division multiplexing system is proposed in this work. The considered channel is selective in time and frequency domain, that is doubly selective channel. Wavelet transform based weighted twin support vector regres...
