This book mainly introduces LTE mobile communication technology and its evolution towards the fifth-generation mobile communication technology, covering the principles of LTE and 5G NR, technical specifications, and LabVIEW implementation. The book analyzes key LTE technologies and related specifications, describes the NSA and SA standards for 5G mobile communication systems, and examines and discusses new 5G mobile communication technologies of interest to the industry. Based on LabVIEW graphical design language and Universal Software Radio Peripheral (USRP), it gives detailed implementations of WLAN and LTE framework, as well as LabVIEW implementations of new waveforms for large-scale MIMO and GFDM in 5G mobile communications.
