In this paper, a new Spatial Modulation (SM) scheme, called Diagonal Space Time Coded Spatial Modulation (DS-SM), is designed by embedding the Diagonal Space Time Code in SM. The DS-SM scheme still inherits advantages of SM while enjoying further benefits from spatial constellation (SC) designs. | Research and Development on Information and Communication Technology Diagonal Space Time Block Coded Spatial Modulation Invited article Nguyen Tien Dong1 Tran Xuan Nam1 Le Minh Tuan2 1 Le Quy Don Technical University Hanoi Vietnam 2 Mobifone R D Center Mobifone Corporation Hanoi Vietnam Correspondence Tran Xuan Nam namtx@ Communication received 27 October 2018 revised 24 December 2018 accepted 26 December 2018 Online early access 28 February 2019 Digital Object Identifier The Area Editor coordinating the review of this article and deciding to accept it was Dr. Truong Trung Kien Abstract In this paper a new Spatial Modulation SM scheme called Diagonal Space Time Coded Spatial Modulation DS-SM is designed by embedding the Diagonal Space Time Code in SM. The DS-SM scheme still inherits advantages of SM while enjoying further benefits from spatial constellation SC designs. Based on rank and determinant criteria a new set of four SC codewords is proposed for the DS-SM system with four transmit antennas to achieve the fourth-order diversity. Then a general design procedure for an even number of transmit antennas larger than four is developed by cyclically shifting two rows of the SC codewords. Simulation results show that DS-SM surpasses several existing SM schemes at the same spectral efficiency and antenna configuration. DS-SM also exhibits better performance than the benchmark systems under spatially correlated channels. The complexity of DS-SM is also analyzed and compared to other SM schemes. Keywords Multiple-input multiple-output MIMO space time block code spatial modulation. I. Introduction Spatial Modulation SM proposed by Mesleh et al. in 1 is a new transmission technique which can overcome many drawbacks of the conventional MultipleInput Multiple-Output MIMO system. Different from the previous MIMO transmission schemes such as Vertical Bell-Labs Layered Space-Time V-BLAST or Space-Time Block Codes STBC the SM .
