Summary	The proposed effort explores enhanced Bandwidth Efficient Modulation (BEM) schemes emphasizing constant envelope modulation, pulse shaping, and Forward Error Correction (FEC) coding. The objective is to identify or devise a BEM scheme that provides very good spectral efficiency in comparison to theoretical limits, provides excellent BEM performance when the satellite transponder includes a Traveling Wave Tube (TWT) amplifier near saturation, and is of sufficiently modest complexity for practical transceivers.
