Abstract
A method for communication includes defining a signal constellation including multiple constellation points in a signal space, such that each constellation point corresponds to a signal representing a respective combination of values of at least three bits, wherein three or more subsets of the bits in each of the constellation points are respectively allocated to three or more data streams. A sequence of signals is received, each signal selected from the signal constellation. The received sequence of the signals is demodulated, and one of the three or more data streams is reconstructed based on the demodulated signals.
