Capacity and BER Performance Analysis of Single Cell Massive MIMO with Various Precoding Techniques
Abstract: AbstractMassive Multi Input Multi Output (MIMO) is one of the promising technologies which will facilitate the 5th generation wireless communication system (5G) in the near future. It also goes by other names such as, large MIMO, hyper MIMO, full-dimension MIMO and ARGOS. In this technology the Base Station is incorporated with a large number of transmitting antennas (e.g., Hundreds, thousands). A large number of antenna help to focus the energy …

Channel Prediction and Estimation Based on Machine and Deep Learning Techniques: A Review
Abstract: Channel prediction estimation in the high- speed mobile environment is a hot issue for 3D massive multiple input multiple output (MIMO) millimeter-wave (mmWave) system. In this environment, the channel has fast time-varying and non-stationary characteristics. And its time-domain correlation coefficient is a time- varying parameter, which makes it difficult for traditional channel estimation methods to capture the channel variations over time and achieve ideal channel estimation performance. A known signal, …

Review And Analysis of Application of Conductive Polymer Composites in Power-Efficient RF Circuits For 5G PAPR Reduction
Abstract: The need for low power RF circuits has gained more importance in the background of fifth-generation (5G) wireless communication systems, since the inherent PAPR characteristic of 5G signals—especially when using orthogonal frequency division multiplexing (OFDM) based techniques—becomes high. This high PAPR limits the efficiency of RF power amplifiers, increases power consumption, and induces thermal management challenges. In this context, conductive polymer composites (CPCs), based on advanced polymer matrices integrated with …
