Software-defined Radios
Software-defined radios (SDRs) are radio communication systems where some or all of the physical layer functions are software-defined. This means that the radio hardware is designed to be flexible and reconfigurable, allowing it to support a wide range of communication protocols and standards. SDRs are capable of transmitting and receiving a variety of signals, including voice, data, and video, and can be used in a range of applications, including military, commercial, and amateur radio. SDRs offer several advantages over traditional radios, including increased flexibility, reduced hardware costs, and improved performance. They also allow for easier upgrades and modifications, as new features and capabilities can be added through software updates.
