1. A method for a wireless receiver to demodulate a message, the method comprising:
a) using a modulation scheme comprising a plurality of modulation states, wherein:
i) each modulation state corresponds to a respective code number;
ii) each modulation state comprises a raw-signal amplitude according to a plurality of predetermined raw-signal amplitude levels, and a raw-signal phase according to a plurality of predetermined raw-signal phase levels;
iii) each modulation state further comprises an I-branch signal having an I-branch amplitude according to a plurality of predetermined branch amplitude levels, and an orthogonal Q-branch signal having a Q-branch amplitude according to the plurality of predetermined branch amplitude levels;
b) receiving a message comprising message elements, each message element comprising a received signal;
c) for each message element, determining, from the received signal, a measured I-branch amplitude, and a measured Q-branch amplitude;
d) for each message element, determining a particular modulation state comprising the predetermined branch amplitude level that is closest to the I-branch amplitude and the predetermined branch amplitude level that is closest to the Q-branch amplitude, and determining the code number corresponding to the particular modulation state; and
e) producing a first demodulation of the message by concatenating the code numbers corresponding to the particular modulation states of the message elements.
