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.
