1. An apparatus, comprising:
an encoder configured to perform error correction using an error correction code on a received signal to generate an encoder signal;
a shell mapper configured to perform shaping on the received signal over two or more groups of carriers with different constellation sizes to generate a shaped signal; and
a modulator configured to generate an output signal based on the encoder signal and the shaped signal.
