Research Abstract: 

Kalman-filter method have been used for the estimation of time-frequency-selective fading channels in OFDM systems, the estimation is based on Comb-type pilot frequencies arrangement, the channel coefficients that belong to the pilot subcarriers are estimated. Then these estimates are interpolated using different types of interpolations like; Low pass interpolation, Spline cubic interpolation or Linear interpolation. The performances of all schemes have been compared by finding Bit Error Rate where BPSK modulation scheme was used.
