TLDR
In this paper, a coded modulation system with continuous phase and a small controlled envelope variation is proposed, which is called the system constrained envelope continuous phase modulation (ceCPM) and shows that there is a gain for ceCPM over CPM under the same spectrum constraint.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/spl plusmn/0.2} the gain for ceCPM is up to 2.5 dB over CPM at symbol error probability 10/sup -3/. We also show that ceCPM performs well with reduced state sequence detection (RSSD).read more

On Power Amplifier Efficiency with Modulated Signals
Tommy Svensson,Thomas Eriksson +1 more
TL;DR: It is shown that for high overall efficiency it is important to operate the amplifier close to the maximum output power level as often as possible, and this has consequences for the resource allocation in especially packet based multicarrier systems.
