Aiming at the lack of signal preprocessing in current rectal signal research, a new 15th-order Newton iterative fast independent component analysis (FastICA) algorithm is proposed to separate the signal. To solve the incomplete problem of the single channel rectal pressure signal, C-C phase space re...
