In order to achieve high throughput and low-power consumption of the transmitter improve error performance receiver, a novel reconfigurable intelligent surface (RIS)-aided code index modulation (RIS-CIM) is proposed in wireless communications. RIS-CIM utilizes spreading convey additional information, which further improves spectral efficiency (SE) receiver by adding adjusting reflected phase shift low-cost reflective elements at RIS-aided relay. To reduce computational complexity incurred...
Code-index modulation (CIM) uses the index of spreading code to convey information, which can be integrated with different kinds MIMO systems achieve higher throughput. This paper proposes a novel CIM-integrated space time shift keying scheme called CIM-STSK. The CIM-STSK system employs three types resources transmit information bits, are Hadamard codes, dispersion matrix indexes and QAM constellation symbols. mathematical expression bit error rate is derived, theoretical analysis validated...
Space-time shift keying (STSK) systems can transmit information in the form of indices activated by dispersion matrices, which allows a high degree freedom system design to balance tradeoff between diversity gain and multiplexing gain. This paper proposes high-rate reflection STSK based on three-dimensional (3-D) constellation reconfigurable intelligent surface (RIS). To implement phase shifting, set matrices (RDMs) are constructed without power limit. improve bandwidth efficiency, an...
Abstract Reconfigurable Intelligent Surface (RIS), which improves the performance of wireless communication systems by controlling reflection/scattering characteristics incident waves without increasing energy consumption, appears as a promising candidate for future systems. In this paper, RIS-based space-time shift keying (STSK) scheme is proposed. On one hand, reflection phase shifts at RIS are optimized channel gain maximization criterion to obtain better RIS-STSK performance; on other...
