主题
- USRP Radio Configuration
Determine which USRP™ radio products to use.
- Single Channel Input and Output Operations
Single input single output (SISO) operations use one transceiver only.
- Multiple Channel Input and Output Operations
Multiple input multiple output (MIMO) operations using multiple transceiver chains.
- Transmit and Receive Using External Clock
An external clock enables you to synchronize the radio with an external clock generator.
- Check USRP Radio Connection
Check radio connection to SDRu blocks and System objects.
- Run in Offline Mode
Running simulations when no radio is connected.
- Query and Set IP Addresses
You can query and set IP address of connected radios.
- Detect Underruns and Overruns
To detect underruns and overruns, use the lost sample indicator.
- Burst-Mode Buffering
To achieve real time performance, enable burst mode.
- Data Frame Lengths
Set data frame length in receiver blocks or receiver System objects.
- Change Transport Data Rate
Set the transport data rate in blocks or System objects.
- Desired Versus Actual Parameter Values
Actual parameter values can vary from your desired setting.
- Supported Data Types
Supported data types for SDRu blocks and System objects.
- Create Standalone Application for USRP Radios Using Standalone Application Complier App
Create and deploy MATLAB® code for a USRP radio using MATLAB Compiler™ and share it royalty-free with other users. (自 R2025a 起)
