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 and multichannel I/O, detect lost samples, apply burst mode buffering, and repeatedly transmit a waveform.

Functions

`sdrrx`	Create receiver System object for USRP embedded series radio hardware
`sdrtx`	Create transmitter System object for USRP embedded series radio hardware
`capture`	Capture contiguous RF data using USRP embedded series radio hardware (Since R2019b)
`designCustomFilter`	Design custom filter for Analog Devices AD9361 RF chip
`info`	Synchronize receiver or transmitter radio settings with radio hardware
`transmitRepeat`	Download waveform signal to radio and repeatedly transmit it over the air

Blocks
