Multiple input multiple output with antenna number modulation and its applications

Abstract

Multi-user applications of multiple input multiple output systems with antenna number modulation (MIMO-ANM) are proposed in this thesis to be used instead of conventional MIMO and its other variations for providing more advantageous and reliable data transmission in future wireless systems. In the MIMO-ANM scheme, the additional data bits are conveyed by changing the number of active transmit antennas instead of their indices. To utilize all available antennas of MIMO-ANM, Multi-User MIMO-ANM and Multi-User OFDM-SNM are proposed in this thesis as novel multi-access data transmission methods that target serving multiple users by dedicating the antennas/subcarriers used for implementing ANM/SNM to serve a far user, whereas the remaining antennas/subcarriers are used to send data for a near user. The acquired results show that MIMO-ANM and its applications for different communication scenarios offer highly competitive performances and desirable benefits for future wireless networks.
