“…Trivedi and Kumar, (2018) used a scheduler based on a standardized SNR for selecting users for data transmission, the scheduler has higher data rate and long-range transmission capabilities without requiring much power or bandwidth. In addition, this paper presents a comparative assessment of the bit error rate (BER) performance of multi-user multiple input multiple output orthogonal frequency division multiplexing (MU-MIMO-OFDM) and MU-MIMO single-carrier frequency-division multiple access (MU-MIMO-SCFDMA) and investigates the impact of various factors, e.g., the CSI imperfections, network heterogeneity, and other factors on the communication transmission; Bai et al (2020) proposed a prediction method based on the long short term memory (LSTM) network and developed an incremental learning scheme for dynamic scenarios, which makes the LSTM predictor run online; (Multiple-Input Multiple-Output, MIMO) system, based on the measured data of 2.35 GHz band in the road-wall scenario, C Xue et al (2021) proposes a Convolutional Long Shore-Term Memory (CLSTM) and CNN combination of Conv-CLSTM channel prediction model for typical channel state information, Les K-factor, RMS delay extension and angle extension characteristics prediction. Son and Han, (2021) proposed the channel adaptive transmission (CAT), which uses the LSTM network for channel prediction and the prediction accuracy is over 97%, indicating that this algorithm can be effectively used for channel prediction.…”
