Abstract :
We have developed a coded modulation system with continuous phase and a small controlled envelope variation called Constrained Envelope Continuous Phase Modulation (ceCPM). For the spectrally efficient scenarios, within the ceCPM framework it is possible to find schemes with an SNR gain up to 2.5 dB over Continuous phase modulation (CPM) at symbol error probability 10-3, under the same requirement on spectral confinement and spectral efficiency as for the best CPM scheme. In this paper we discuss the design process for how to obtain such ceCPM schemes, and we elaborate on the properties of these ceCPM schemes.
