무선통신 I/O

실제 RF 신호 송신 및 수신

실제 RF 신호를 송신하거나 수신할 때는 I/O 속성과 기법을 사용하여 단일채널 및 다중채널 I/O를 수행하고, 손실된 샘플을 감지하고, 버스트 모드 버퍼링을 적용하고, 파형을 반복적으로 송신합니다.

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.
