Performance Enhancement of OMP Algorithm for Compressed Sensing Based Sparse Channel Estimation in Otion using the same number of pilot subcarrier. The added computational complexity is studied and several methods are suggested to keep it minimal while still achieving the performance gain provided by the LMMSE-OMP including using compressive sampling matching pursuit (CoSaMP) CS algorithm for the

ICI Mitigation for High-Speed OFDM Communications in High-Mobility Vehicular Channelsnce in the time domain is transmitted, and both channel amplitudes and Doppler shifts are estimated in time domain. Then, the complete frequency domain channel matrix is constructed from the estimated parameters and used for ICI mitigation. In contrast to conventional methods that only estimate diag
