The Capacity of Noncoherent Continuous-Phase Frequency Shift Keying

Abstract—Capacity analysis is used to determine the fundamental tradeoff between power and spectral efficiency for coded continuous-phase frequency shift keying (CPFSK). The modulation may use an arbitrary modulation index h and the number of tones M may be any power of two. Detection is noncoherent and the channel is either AWGN or fully-interleaved (ergodic) Reyleigh fading. Numerical results demonstrate the advantage of using nonorthogonal modulation and multiple tones when the bandwidth requirement is tight.
