Modulation Technique for Software Defined Radio Application

چکیده
The role of radio in the communication systems have been extended from simple radio to mobile communications and beyond. Minimization or the replacement of hardware in communication technology through software has been resulted in the birth of a new technology, widely known as Software Defined Radio (SDR). This paper deals with the development of SDR to transfer information from one place to another place through channel. The incoming analog signal is modulated using phase shift keying (PSK) type modulation. Then add noise or interference to the channel. The transceiver is demodulated the modulated signal in order to retrieve the transmitted information. The results are confirmed that the programmed SDR can demodulate the various kinds of audio signal or any signal by software programming.

ASoftware Defined Radio (SDR) system is a radio communication system, which uses software for modulation and demodulation of radio signals. In software defined radio (SDR) receivers, high-precision clock with very low jitter is required. It is intuitive to use only one fixed master clock. However, different wireless standards use different master clock rates. Under such circumstances, digital s...
