This paper deals with multilevel coded modulations (MLC) based on ASK and PSK constellations for the AWGN channel. Under multistage decoding (MSD) and when block partitioning is applied to an asymmetric constellation, we show that the capacity of the modulation can be attained using constituent codes with equal signaling rates at each level. For finite code length N, performance is derived analytically by evaluating Gallager's coding exponent.
