ABSTRACT
We present the co-channel interference mitigation in the time-scale domain (CIMTS) algorithm which estimates the signal of interest (SOI) and the interfering signal from their superposition in the presence of additive noise. This method is inspired by the reconstruction of the interference from the null space of the SOI in the time-scale domain. Once the null space of the SOI is determined, the interfering signal is reconstructed via a set of linear operations. Then, the SOI is estimated by a simple subtraction of the estimated interference from the observations.<>
