To launch labAlive simulation applications you need a Java Runtime Environment supporting Java Web Start on your system. Here you can get more information about installing the right Java version.
An audio signal is modulated and the transmitted signal is logged to a file. Create the folder C:\labAlive\UHD manually before starting the simulation!
- An audio signal m(t) is streamed from the server. 44100_mono_demo.wave
- After six-fold upsampling the rate is 264.6 kHz.
- Every 2000 samples the modulation frequency changes, i.e. 7.56 ms.
- Within this time the value of the digital symbol determines the frequency shift, e.g. 3 V - 30 kHz.
- After a frame of 14 symbols the cycle is repeated, i.e. 105 ms.
- The transmitted signal s(t) is recorded to a file samples_short_0.dat at C:\labAlive\UHD.
- You might press F3 to accelerate the simulation speed (F2 to reduce it).
- Listen to the audio signal. Press F3 several times till real time audio speed is reached.
- A further simulation will be provided to transmit and receive the signal via USRP.
- A further simulation will be provided to demodulate the signal.
Transmitted signal samples are logged.
