    Are Software-Defined Radios a big change?
    There’s been a lot of excitement around the recent proliferation of software-defined radios. For those in the industry more familiar with traditional radios, this shift to SDR might be a big change, while for others it might be a welcome sign. It’s important to understand the difference between SDR and traditional or hardware-defined radios.

    What is software defined radio (SDR)?
    As the name suggests Software Defined Radio is the wireless communication system operating at radio frequency and configurable using software. In SDR, hardware components commonly available in analog counterpart are configured in software which is ported either on FPGA or DSP to be used in wireless chain.

    Is a software-controlled radio an SDR?
    For example, if a radio has hardware for both frequency modulation and amplitude modulation and allows the user to choose between the two by means of a software (or firmware) setting, we are not dealing with SDR. This might be called a software- controlled radio. A fully-hardware-based digital data link is not an SDR.

    Is a hardware-based RF communication system an SDR?
    A typical hardware-based RF communication system that can be modified in some way via software is not an SDR. For example, if a radio has hardware for both frequency modulation and amplitude modulation and allows the user to choose between the two by means of a software (or firmware) setting, we are not dealing with SDR.
