Implementation¶

In order to test our communication chain, we decided to implement a receiver to see if we could receive the temperature and print it on the screen. To do that, we started with the receiver that was implemented to receive the GPS signal in a former project since we use the same waveform. In order to apply the receiver to our case, we had to remove the part that was linked to the RTTY system with the Baudot and ASCII Coding. Since we wanted an integer to indicate the temperature, that is what we implemented.

Subdemod.vi¶

We decided to use the same start sequence that the one of the GPS project and to use as well Manchester coding. Therefore, we only changed the last part about Baudot and ASCII coding.
