| Abstract: | The application of regularized orthogonal match pursuit(Regularized OMP) algorithm in channel estimation of UWB system is studied.When ROMP is applied in sparse signal recovery,it features the high speed and low computation complexity of greedy algorithm.The channel estimation of UWB system is required to estimate a group of parameters of the maximum diameters,and ROMP has the ability to reliably recover noise-contained approximately-sparse signal,which makes it suitable for UWB channel estimation.Through s... |
