Empirical Mode Decomposition based Adaptive Filtering for Orthogonal Frequency Division Multiplexing Channel Estimation
This paper presents an empirical mode decomposition (EMD) based adaptive filter (AF) for channel estimation in OFDM system. In this method, length of channel impulse response (CIR) is first approximated using Akaike information criterion (AIC). Then, CIR is estimated using adaptive filter with EMD decomposed IMF of the received OFDM symbol. The correlation and kurtosis measures are used to sel...

متن کاملEstimation of Channel Impulse Response by Deconvolution Method
This paper describes deconvolution method for estimation of channel impulse response. Radio channels in radio system can be completely described by channel impulse response. We can investigate radio channel type from channel impulse response. In environment between transmitter and receiver there exist two main propragation components, Line-of-Sight (LOS) and Non-Line-of-Sight (NLOS), which are ...
