Improved Tomlinson–Harashima Precoding for Ultra Reliable Communication in Intelligent Transportation Systems by Shibiao He, Xinyi Yang, Yong Liao

“…Aiming at the technical challenges of information transmission caused by the fading effect and the fast time-varying characteristics of the channel for C-V2X communication, an improved Tomlinson–Harashima precoding (THP) algorithm for multiple input multiple output (MIMO) systems is proposed. Channel state information (CSI) and correlation are exploited to compensate instantaneous CSI, which could reflect current real-time channel status exactly. …”

Joint optimization of dispersion matrix and 3D constellation for STSK system based on improved genetic algorithm by Xiaoping JIN, Jiayu LIU, Chen JIANG, Qiang GUO

“…Space-time shift keying (STSK) is a modulation scheme used in multi-input multi-output (MIMO) communication systems.It uses a pre-designed dispersion matrix set (DMS) to realize the flexible design of the system between multiplexing and diversity.An improved genetic algorithm (GA) was proposed to assist the joint optimization of DMS and 3D constellations, that is, the DMS and 3D constellations were jointly coded as the chromosome of GA , and the coding gain corresponding to the rank and determinant criterion was adopted as the overall fitness value.Through efficient selection and improved mutation and crossover strategies, DMS and 3D constellations with low bit error rate (BER) can be obtained.At the same time, the symmetry of the 3D constellation was used to greatly reduce the computational complexity of according to the fitness value the coding gain.The theoretical average paired error probability (ABEP) of the 3D STSK scheme was deducted.The simulation results show that, compared with the traditional GA and random search schemes, the improved GA proposed can significantly reduce the complexity of system implementation while ensuring BER performance.…”

Research on characterization and modeling for 3D wideband time-varying channels for urban microcells at 2.55 GHz by Shu LI, Xiong-wen ZHAO, Rui ZHANG, Qi WANG, Sui-yan GENG

“…Based on the outdoor microcell MIMO channel measurement campaign at 2.55 GHz,the time-evolution characteristics of three-dimensional wideband channel were studied.The SAGE algorithm was used to extract multipath parameters such as azimuth and elevation angle of departure and arrival.A bidirectional matching algorithm was applied to tracing multipath and the ＆quot;birth-death＆quot; process.The statistical characteristics of multipath birth,lifespan,multipath initial and evolution parameters were analyzed and modeled based on the cross-correlations of multipath parameters.A time-varying channel model with multipath birth-death process was developed.The model parameter table and a detailed flowchart were offered for time-varying channel simulations.The proposed model was validated by comparing the root-mean-square (RMS) of delay spread and angular spread between the simulated and measured results.The channel model proposed can be applied in time-varying channel simulation for urban microcells and it’s also very important to be referred in 5G dynamic channel modeling.…”

Online Fault Detection Approach of Unpredictable Inputs: Application to Handwriting System by Ines Chihi, Mohamed Benrejeb

“…This approach allows connecting inputs (IEMG signals)/outputs (pen tip coordinates) data as a parametric model for Multi-Inputs Multi-Outputs (MIMO) system. The proposed approach is considered as a model-independent abrupt or intermittent fault detection method and as an alternative solution to the unpredictable input observer based techniques, without any observability requirements. …”

Fully Pipelined Implementation of Tree-Search Algorithms for Vector Precoding by Maitane Barrenechea, Mikel Mendicute, Egoitz Arruti

“…The nonlinear vector precoding (VP) technique has been proven to achieve close-to-capacity performance in multiuser multiple-input multiple-output (MIMO) downlink channels. The performance benefit with respect to its linear counterparts stems from the incorporation of a perturbation signal that reduces the power of the precoded signal. …”
