Frequency‐hopping signals sorting based on underdetermined blind source separation
Most of the earlier approaches for frequency‐hopping (FH) signals sorting with a single sensor do not adapt to synchronous network, whereas the multiple‐sensor‐based algorithms request the number of sensors must be more than that of signals.

SECOND ORDER BLIND IDENTIFICATION OF SINGLE-CHANNEL SIGNAL BASED ON KERNELS
Weight-adjusted variant second order blind identification( WASOBI) algorithm had been used in fault diagnosis field,but it couldn’t separate source signal when the observation signal’s dimension was insufficient.

Jammer Suppression in DS-CDMA Communications using Parafac-based Blind Separation
In this paper we propose to apply parafac-based source separation techniques for jammer suppression in direct spread spectrum communication systems. The jammer excision is formulated as an optimization problem and a new algorithm is presented which is ...
