Abstract
Improved decision boundaries of narrowband M-ary CPFSK with LDI, DC, a nd CDDD receivers are reported at modulation index 1/M. A simple metho d to determine each improved decision boundary by considering only the two closest symbols to that boundary is discussed. Numerical results presented for quaternary and octonary signals indicate that improved b oundaries are almost identical to optimal boundaries and perform signi ficantly better than the standard boundaries.
