Radio I/O

Transmit and receive real-world RF signals

When transmitting or receiving real-world RF signals, use I/O properties and techniques to perform single channel I/O, detect lost samples, apply burst mode buffering, and repeatedly transmit a waveform.

Functions

`sdrrx`	Create receiver System object for radio hardware
`sdrtx`	Create transmitter System object for radio hardware
`capture`	Capture RF signal data using SDR device (Since R2019b)
`designCustomFilter`	Design custom filter for Analog Devices AD936x RF chip
`info`	Obtain radio information
`transmitRepeat`	Download waveform to radio and repeatedly transmit it over the air

Blocks

Pluto Receiver	Receive data from Analog Devices ADALM-PLUTO radio
Pluto Transmitter	Transmit data to Analog Devices ADALM-PLUTO radio

Objects

`comm.SDRRxPluto`	Receive data from Analog Devices ADALM-PLUTO radio
`comm.SDRTxPluto`	Transmit data to Analog Devices ADALM-PLUTO radio

Topics

Channel I/O
Use ADALM-PLUTO radio channels to send and receive data.
Repeated Waveform Transmitter
Use a transmitter System object™ for repeated signal transmission.
Detect Underruns and Overruns
To detect underruns and overruns, use the lost sample indicator.
Burst Mode
To achieve real time performance, enable burst mode.

Capture RF Data to Baseband File Using ADALM-PLUTO Radio

Use the capture function and an ADALM-PLUTO radio to record RF signals for post-capture processing in MATLAB®. Save an FM broadcast signal to a file as baseband samples. Read the file containing the recorded signal and demodulate the baseband samples.
