  • Patent number: 9960831
    Abstract: A communication system for the next generation wireless communications technology standards. The communication system architecture is created by the combination of the index modulation technique and the multiple input multiple output orthogonal frequency division multiplexing which eliminates the need to utilize complex equalizers by parsing high speed data strings and transmitting them over multiple orthogonal subcarriers, and allows the bits to be transmitted via active subcarrier indices. The OFDM-IM and multiple input multiple output communication techniques are used in tandem. The communication system can be used in future generation mobile communication systems and standards (5G and beyond), Local Area Network system and standards, terrestrial digital TV system and standards, multi-carrier communication systems and broadband digital communication systems.
