The SIMO system model.
(Color online) Simulation setup and acoustic ray paths of a shallow water multipath environment.
Impulse responses of two underwater acoustic channels and blind estimates of the BP, OMP, MP, subspace, and LS methods. The left side shows the results of channel 1 while the right side displays those of channel 2.
(Color online) Correlation coefficients versus SNR.
(Color online) Correlation coefficients versus transmitted signal length.
Top view of the simulated room used to evaluate the performance of the blind multichannel identification algorithm.
Comparison of room impulse responses between true acoustic channels and their estimates obtained by the BP. The three figures on the left side are the true responses of the three channels while the right side displays the estimated results.
