1. A method of operating a first electronic device to transmit a first data symbol to a second electronic device, the method comprising:
with one or more processors, generating, based on a transmit modulation constellation, a dictionary having a set of items, each item in the set of items corresponding to a different respective information value for the data first symbol and each item in the set of items including multiple points from the transmit modulation constellation;
with the one or more processors, generating modulated data by modulating the first data symbol onto a point from an item in the dictionary;
with the one or more processors, generating a second data symbol based on the modulated data; and
with one or more antennas, transmitting a radio-frequency signal that includes the second data symbol.
