Abstract:
1. A method for transmitting data to one or more receivers linked to a transmitter by a wireless channel, the method characterized by: (a) separating the data into one or more layers, each layer represented by one or more bits; (b) combining the bits of the layers into a bitstream, each possible bitstream combination being representable by a unique data point; (c) generating a modulated signal by modulating the bitstream with a first modulation scheme, the modulation scheme operable to modulate at least as many unique data points as there exist possible bitstream combinations; and (d) transmitting the modulated signal to the one or more receivers, each receiver operable to demodulate at least one of the layers using the first modulation scheme or one or more other modulation schemes, the other modulation schemes operable to demodulate a signal having fewer possible data points than is the first modulation scheme.
