摘要： A method based on orthogonal frequency division multiplexing (OFDM) called OFDM-subcarrier gap and index modulation (OFDM-SGIM) is proposed in which the gaps between the active subcarriers are exploited to transmit extra bits alongside the conventional QAM symbols. Thereafter, the index modulation is combined with the new proposed OFDM-based scheme to guarantee a fixed subblock size.

摘要： A system and method for providing confidentiality against eavesdropping and authentication against impersonation attacks for advanced wireless communication systems are disclosed. The method exploits ARQ as a MAC layer mechanism and artificial noise as a physical layer mechanism with maximal ratio combining to achieve secrecy. An artificial noise, not requiring class space in the channel, is designed and added to the data package based on the QoS requirements and channel condition between legitimate parties. Basically, a special AN, which does not require null-space in the channel, is designed based on the QoS requirements and the channel condition between the legitimate parties and injected to the data packet. If the same packet is requested by the legitimate receiver (Bob), an AN cancelling signal is designed and added to the next packet. Then, an AN-free packet is obtained by using MRC process at Bob, while deteriorating the eavesdropper's performance.

摘要： The method is related to the smart frame design that contains multi-user single-carrier (SC) transmission to support 5G-and-beyond communication systems that permit enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable low-latency communication (URLLC) services. The method enhances the capacity of the system in line with the filter parameters to be selected according to the user's requirements and to meet the requirements of the desired and adjacent users.
