In high-speed mobile scenarios, conventional estimation schemes for millimetre-wave multiple-input multiple-output (MIMO) communication systems may fail to track of time varying channels, so this paper proposes an efficient channel estimation scheme for time-varying millimetre-wave channels. Since the arrival/departure angles (AoAs/AoDs) vary much slower than the path gains, the channel estimation...Show More
Rapid advancements in areas like new energy generation systems, energy conversion equipment, and electric vehicles have necessitated capacitor films with high comprehensive energy storage performance. In contrast, current commercially biaxially oriented polypropylene film (BOPP) is gradually unable to meet diverse requirements, particularly in terms of energy storage density and operating temperat...Show More
Three-Dimensional Multiple-Input Multiple-Output (3D-MIMO) system can effectively improve the spectrum efficiency(SE) and user experienced data rate for future wireless communication systems. However, the dramatic increase of users and antennas brings problems such as decreased estimation accuracy and increased complexity to 3D-MIMO channel estimation. This paper proposes a graph-regularization-ba...Show More
Based on the Xilinx Zynq-7000 platform and the Vivado SDK toolbox, the C model of the matrix SVD decomposition module is established, and the writing, compiling and debugging of the matrix SVD decomposition module code are completed. Then simulate in the hardware development environment and perform functional tests on the Zedboard development board. Through the simulation and testing of the hardwa...Show More
