Abstract :
We develop a coded modulation system with continuous phase and a small controlled envelope variation. We call the system constrained envelope continuous phase modulation (ceCPM) and show that, there is a gain for ceCPM over CPM under the same spectrum constraint. With normalized amplitude varying in the interval {1±0.2} the gain for ceCPM is up to 2.5 dB over CPM at symbol error probability 10-3. We also show that ceCPM performs well with reduced state sequence detection (RSSD).
