Abstract
A method of transmitting and receiving data using superposition modulation in a wireless communication system having multiple antennas is disclosed. More specifically, the method comprises encoding the at least one inputted data stream by a channel coding scheme, puncturing the at least one inputted coded data stream into at least two sub-streams, layer-modulating the at least two sub-streams using layer-modulation schemes, transmitting the layered-modulated sub-streams via the multiple antennas, wherein transmission power of each antenna is based channel condition, and receiving by at least one user the layered-modulated sub-stream, wherein the each user uses different demodulation scheme.
