Abstract
Abstract A time delay estimation(TDE) method for MIMO systems, using combined continuous wavelet transform(CWT) and cross correlation method, is proposed. By calculating and handling the cross correlation between the CWT coefficients of system input and output data, a series of time delays over scales (frequencies) are calculated and an unbiased estimation is deduced from them. The TDE method under closed loop case is also studied. The numerical examples with simulation as well as experimental data verify that the procedure works well.
