NAME SDR - Software-Defined Radio SYNOPSIS use SDR; my $radio = SDR->radio(can => 'rx'); $radio->frequency(104_500_000); $radio->sample_rate(2_000_000); $radio->rx(sub { ## process IQ samples in $_[0] }); $radio->run; DESCRIPTION This is the parent module and primary interface for the SDR system of perl modules. SDR stands for Software-Defined Radio. It is a technology where raw radio samples are created and decoded purely in software -- kind of like a "sound card for radio". It's exciting because a single device can communicate using many different modulations and protocols, usually across a large range of frequencies. It provides a wrapper around certain tasks like creating a radio with the "radio" method and creating an audio sink with the "audio_sink" method. There are also some handy utilities in SDR::DSP. When creating a radio, you specify what capabilities you want the radio to have (currently either "tx" or "rx"). The "radio" method will figure out which SDRs you have drivers installed for and which, if any, are currently plugged in. It will use the first suitable one it can find. NOTE: The current radio drivers create background threads so you shouldn't fork after you create instances of any radio objects. DRIVERS SDR::Radio::HackRF - Can transmit and receive. SDR::Radio::RTLSDR - Can only receive. SEE ALSO SDR github repo <https://github.com/hoytech/SDR> The examples in the "ex/" directory of this distribution.
