Abstract

A possible approach to address spectrum congestion is to develop signaling schemes that allow for spectrum sharing with minimum system interference. In this paper, we consider the problem of co-existence between radar and communications systems by designing a common signaling scheme to jointly optimize the performance of both systems. In particular, we derive constraints on the parameters of linear frequency-modulated signals to minimize the interference between the two systems as well as the interference between multiple communications users. We propose a multi-objective optimization scheme for a pulse-Doppler radar system and a multiuser communications system, and we consider the trade-offs in performance under various system constraints.
