Abstract :
We present a new approach for designing the continuous phase frequency shift keying (CPFSK) system which is a nonlinear mapping of the M-ary symbols into the N-ary CPFSK. In this approach we can design a M-ary symbol nonlinear CPFSK (NCPFSK) system of simple structure. The proposed M-ary NCPFSK is a modification of multi-h CPM (MHCPM) scheme. The proposed modulation improves the performance relatively over the conventional modulation schemes
