| Abstract(in English) | Accurate channel estimation is necessary for coherent detection of the orthogonal frequency division multiplexing (OFDM) signals. In this paper, a pilot-assisted adaptive interpolation channel estimation is proposed. One- and two-dimensional adaptive interpolation filtering methods are presented for frequency-multiplexed pilot, time-multiplexed pilot and scattered pilot cases. Interpolation filter tap weights are adaptively updated according to the normalized leaset mean square (NMLS) algorithm. The average bit error rate (BER) performance in a doubly-selective Rayleigh fading channel is evaluated by computer simulation. It is confirmed that the proposed two-dimensional adaptive interpolation channel estimation is very robust against doubly-selective fading and provides BER performances close to the ideal channel estimation case. |
