and Higher - Order Statistics A plied in the Detection of Human Nerve

A CT Due to the very low signal levels (pVolts) and the signi~cantly higher levels of interference from adjacent muscles and other noise sources), the overall signal-t~noise ratios (SNRs) of human nerve signals ~ e c ~ r ~ e d ~ r o m whole-cufl electrodes is very poor. T y p ~ c ~ l ~ , non-real-time methods (ensemble ~ e r ~ g i n ~ ) are used to contend with these poor However, if these signals are to be useful in p r ~ ~ ~ i n g real-time information (in a closed-loop control system), other methods must be employed To this end, subspace analysis methods using the eigenvalues of the autocorrelation (a Yd order statistic) and cumulant (a Yd order statistic) matrices of time-series samples were evaluated
