Spatial modulation in a wireless communications network

A method, comprising:

• (a) receiving a wireless signal from a remote device,
• (b) obtaining a first information sequence from the wireless signal through a first demodulation technique;
• and
• (c) obtaining a second information sequence from the wireless signal through a second demodulation technique, wherein the second demodulation technique is a spatial demodulation technique.

An apparatus, comprising:

• a first antenna at a first location;
• a second antenna at a second location;
• a first modulator configured to generate a signal that conveys a first information sequence
• a second modulator configured to spatially modulate the signal to further convey a second information sequence, wherein the second modulator directs the signal to the first antenna when the second information sequence has a first value and directs the signal to the second antenna when the second information sequence has a second value.

An apparatus, comprising:

• a plurality of antennas;
• a first demodulator configured to obtain through spatial demodulation a first information sequence from a plurality of signals received from the plurality of antennas;
• and to generate a representative signal of the plurality of signals;
• a second demodulator configured to obtain a second information sequence from the representative signal.
