We propose a bandwidth limiting type spread spectrum communication for application to development of frequency resources. First, we estimate the effect of bandwidth limiting, and evaluate the possibility of frequency-division multiplexing. Second, to reduce interference in existing signals, we estimate their susceptibility to interference by using a trapfilter circuit. Third, majority decision logic is proposed to realize amplitude limiting type code-division multiplexing easily. Our results confirm the effectiveness of this method.
