The Generation of Cosine Pulse Signal with Four Phase Codes

This paper introduces the concept of cosine pulse signal with four phase codes and analyzes the frequency spectrum of the signal and its main characteristics. Two circuit approaches which generate the cosine pulse signal with fourphase code are proposed and some applications with this kind of signal are offered in this paper as well.
