Comparing Various Channel Estimation Techniques for OFDM Systems Using MATLAB

This paper compares the performance of various channel estimation techniques for OFDM systems over quasi-static channels using MATLab.It compares the performance of five channel estimation techniques, these are: decision directed (DD), linear interpolation, second-order interpolation, discrete Fourier transform (DFT) interpolation, minimum mean square error (MMSE) interpolation.The performance is evaluated in terms of two widely-used performance...
