A software-defined radio platform is used in the software-defined radio architecture to set the radio frequency, bandwidth, modulation, error correction, and power. A new era of wireless communications is being ushered in by software-defined radio (SDR). Old analogue systems are quickly being replaced by SDR as the preferred choice for a range of wireless applications because it allows for wireless applications that would not be practical with them. Military applications use SDR, which is viewed as a potential technology for cellular networks in the future. SDR’s key advantage is its adaptability; the functionality is implemented in software, making it simple to change.
