CS-UWB Channel Estimation via Optimized Sensing Matrix

Abstract:

In order to obtain accurate Compressive Sensing UWB (CS-UWB) channel estimation coefficients, a method of constructing adaptive sensing matrix is proposed via incoherence criterion, making the greedy reconstruction algorithms obtain optimal atoms from redundancy dictionary. The modified OMP algorithm without a prior of sparsity and SNR information is also presented for convenient using. Simulation results show that much improvement on UWB channel estimation is obtained based on the adaptive sensing matrix using the proposed algorithm.
