摘要: Optimized phase pulses, which maximizes the minimum Euclidean distance in spectrally constrained partial response CPM for di erent pulse lengths and alphabet sizes, are numerically found. The channel is an AWGN by a narrow spectrum mask, puts hard requirements on both width of spectral main lobe size side lobes. parameterized equidistant sample points connected cubic spline interpolation modulation index also treated as free parameter. It found that optimized pulses smooth many cases similar to GMSK family. A gain up 0.9 dB obtained compared useful property reduced complexity detection some pulses.
