Key Features of SDR
- Flexibility in configuring radio parameters
- Ability to support multiple communication standards
- Cost-effectiveness due to reduced hardware requirements
- Enhanced scalability and adaptability
SDR technology has revolutionized the way we approach wireless communication, offering a more dynamic and efficient solution compared to traditional hardware-based systems.
History of SDR
The concept of SDR dates back to the late 20th century when researchers began exploring the potential of using software to control radio functions. The first practical implementation of SDR emerged in the 1990s, primarily driven by military applications. Over the years, advancements in digital signal processing and computing technologies have facilitated the widespread adoption of SDR across various industries.
SDR Architecture
SDR systems typically consist of three main components: the antenna, the analog-to-digital converter (ADC), and the digital signal processor (DSP). The antenna captures radio signals, which are then converted into digital signals by the ADC. The DSP processes these digital signals, enabling the implementation of various radio functions through software.
