On the exact formula for the minimum squared Euclidean distance of CPFSK
N. Ekanayake, Ranjith Liyanapathirana · IEEE Transactions on Communications · 1994
In a paper by Rimoldi (see ibid., vol.39, no.9, p.1280, 1991) the closed-form expression for the minimum squared Euclidean distance of continuous-phase frequency-shift-keyed (CPFSK) signals with modulation index h/spl les/1/2 was derived. The authors extend the result derived by Rimoldi to include any rational modulation index.>
