Ubiquitous networking is the need of present scenario that ensures continuous connectivity throughout the environment. Future Network requires high level robustness with minimal OOB emission, flexibility as well as efficient performance.This book is about the modulation techniques used in 5G, Generalized Frequency Division Multiplexing (GFDM) which is adjustable and reliable multicarrier modulation technique with better level of performance and latency rates.6G experimental layout has been suggested in the book which will help in further development of high frequency wireless network ranging...
