Low-Complexity Differential Spatial Modulation Schemes for a Lot of Antennas
IEEE Access, 2020 Spatial modulation (SM) uses a single antenna for transmission each time to avoid synchronization and interferences among transmitter antennas, and differential SM (DSM) is a kind of SM technique that does not need pilot symbols and channel estimation ...

Improved Schemes of Differential Spatial Modulation
IEEE Access, 2021 Differential spatial modulation (DSM) is able to transmit additional data bits without increasing the number of radio-frequency chains and power consumption and also avoids pilot overhead.

Long-Block Differential Spatial Modulation
IEEE Access, 2023 Spatial modulation (SM) can transmit additional data bits by selecting antennas and avoids synchronization and interferences among antennas. Differential SM (DSM) is a noncoherent technique of SM, but it is less bandwidth efficient than SM.

Secure Cognitive MIMO Wiretap Networks With Different Antenna Transmission Schemes
IEEE Access, 2021 This paper investigates a secure transmission in the multiple-input multiple-output (MIMO) cognitive wiretap networks, where a secondary transmitter (Alice) sends data to a secondary receiver (Bob) in the presence of an eavesdropper (Eve).

Differential spatial modulation for high-rate transmission systems
EURASIP Journal on Wireless Communications and Networking, 2018 This paper introduces a new differential spatial modulation (DSM) scheme which subsumes both the previously introduced DSM and high-rate spatial modulation (HR-SM) for wireless multiple input multiple output (MIMO) transmission. By combining the codeword

Differential spatial modulation scheme based on orthogonal space-time block coded
Tongxin xuebao, 2017 Focusing on the problem that differential spatial modulation (DSM) couldn’t obtain transmit diversity and has high decoding complexity,a new differential spatial modulation scheme based on the orthogonal space-time block code was proposed and the ...
