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
`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

E3xx Receiver	Receive data from USRP E3xx radio hardware
E3xx Transmitter	Send data to USRP E3xx radio hardware

Objects

`comm.SDRRxE3xx`	Receive data from USRP E3xx radio hardware
`comm.SDRTxE3xx`	Send data to USRP E3xx radio hardware

Topics

Channel I/O
Overview of available radio channels to send and receive data.
Repeated Waveform Transmitter
Use a transmitter System object™ for repeated signal transmission.
Capture Over-the-Air Signals
Record RF signals for post-capture processing in MATLAB^®.
SDR Receiver Sample Times
Set sample times in receiver blocks or receiver System objects.
Data Frame Lengths
Set data frame length in receiver blocks or receiver System objects.
Detect Underruns and Overruns
Detect underruns and overruns using the lost sample indicator.
Burst Mode
To achieve real time performance, enable burst mode.
Apply Conditional Execution
To determine whether you receive valid data from the radio hardware, apply conditional execution.
