Software-defined radio~(SDR) has been emerging for many years in various fields, including military, commercial communication systems, and scientific research, e.g. space exploration. GNU Radio is an open source SDR framework written in Python. This talk will introduce from basic concept of software-defined radio and various front-end hardware, and then illustrate how to use Python to develop SDR.
