The transform selective interference suppression algorithm (TSISA) has been proposed earlier for excising interfering signals in different transform domains. The proper domain is selected using a compression gain metric, and the interference excision is done using the forward consecutive mean excision (FCME) algorithm in that domain. This paper investigates the domain selection process of the TSISA via computer simulations. Interfering signal types considered are impulses, sinusoids, chirps and band-limited binary phase-shift keying (BPSK) communication signals. The results confirm that the TSISA is capable to choose the most suitable transform for the interference excision. The stronger the interfering signal is the more frequently the TSISA is able to choose the most suitable transform domain. 1.
