SISO OFDM GUI

→



Interface:

Click the START button to get it working.

Users can choose other modulations (QPSK/16QAM/64QAM/256QAM/1024QAM).

The GUI is divided into five blocks.

(1)

OFDM parameters: If users want to change the OFDM parameter setting, users need to press

STOP again, then press START to read the parameters and bulid a new OFDM signal.

Users can choose other modulations (QPSK/16QAM/64QAM/256QAM/1024QAM).

If run the default setting, it is executed in order.

(2)

Set TX attenuation / RX Gain

(3)

Select Transmit Mode

(4)

Record data: Users can record three types of files(mat/csv/txt).

(5)

Performance Result: Tick to show the performance result (EVM & SNR).
