High mobility channel estimation
WebJan 10, 2024 · In this paper, we propose a novel channel estimation algorithm based on Long Short-Term Memory (LSTM) for UAV air-to-ground transmission to obtain Channel State Information (CSI). To estimate the current slot CSI, we construct the input, forget, and output gates to learn the time correlation of UAV channel. WebIn high-speed railways, the wireless channel and network topology change rapidly due to the high-speed movement of trains and the constant change of the location of communication equipment. The topology is affected by channel noise, making accurate channel estimation more difficult. Therefore, the way to obtain accurate channel state information (CSI) is the …
