EXPERIMENTAL RESULTS

As our goal was to do localization on basis of TOA. So, we searched for different transceivers and came across different transceivers including nrf24l01 and USRPs.

FINAL SETUP

We used three GNU radios as receivers and one as transmitter. For this purpose, we need to know coordinates of the receivers which we are going to be used to locate the source transmitter so we figure out the coordinates for the transmitter by figuring out the length width of the table.

PROCEDURE OF EXPERIMENT

We make custom blocks for receiver and transmitter on GNC using C++ computer language. We have a transmitter and a receiver.
Now, Packets which transmitter sends using our self written custom blocks integrated with USRPS. 
On the other hand, when packet is received on receiver side we see output on the graph integrated with USRPs.

TRANSMITTER

In this flowgraph packets are being sent and that are multiplied by a constant to ensure that the signal is not chopped off during transmission or receiving. Values of those packets are shown in the following GUI scope and its FFT is also shown below to have visualization of the frequency being achieved during the experimentation.
