How the functionality of SDR is realized?
The functionality of Software-Defined Radio (SDR) is realized through the collaborative design of hardware platforms, software algorithms, and open architectures. Its core principle involves dynamically defining communication functions through software programming on universal hardware, replacing traditional dedicated hardware circuits.
I. Technical Architecture: The Foundation of SDR Functionality
II. Key Hardware Platforms: The Physical Carrier for Function Implementation
III. Software Framework: The Core Toolchain for Functional Definition
IV. Functional Implementation Mechanism: The Workflow of Hardware-Software Collaboration

The essence of SDR functionality implementation lies in"universal hardware platforms + software-defined functions": The hardware layer provides high-speed signal acquisition and processing capabilities (ADC/DAC + DSP/FPGA). The software layer defines communication behaviors through algorithm libraries (e.g., GNU Radio) and frameworks (e.g., SCA). Open architectures (bus-based/switched) enable efficient collaboration between modules, ultimately achieving the goal of"multi-mode programmability and software-defined functionality."

This architecture not only represents a revolution in communication technology (the third major shift after analog→digital) but also serves as a core enabling technology for 6G intelligent wireless networks.
