Blind source separation using reference signals (BSSR) is very useful especially when target signals have distinctive features, where the performance of separation is known to have robustness against uncertainties of the reference signals. Here, detail properties of the robustness were investigated by diluting spike waves composed of the reference signal, widening the spikes, and altering the order of evaluation function. Increased dilution rate and wider spikes were found to deteriorate the performance of BSSR; the 4th order of correlation evaluation was shown to be optimal. These results are expected to be helpful for optimal design of reference signals. |
