This book as the title suggests is written with an intention to get familiar with the concepts of Software Defined Radio and hardware/software that help in wireless system design. After extensive survey we found that adopting open source software/hardware could be right fit and hence the use of GNU Radio like open software and USRP open hardware has been used for all experiments throughout the book . Given this reason the book should serve as a good practical guide with detailed steps to follow through to reproduce results as mentioned in the experiments.
