As a high efficiency digital modulation and demodulation scheme, 16-QAM is widely used in HDTV, satellite communication, microwave communication and so on. In the communication system, the method of modulation and demodulation based on soft-defined radio (SDR) is the aim of the development of technology. SDR is a kind of new technology in communication area.
