Received signal strength

Xin Chen

Start a simple test run with our setup. we have an TX on top of the roomba and two RX on the edge of the foam, TX is transmitting signal at 915MHz. We can see from the video, as the robot is approaching the RX, it received signal with higher power, which make sense intuitively. The attached is the transmited signal in baseband and received signal in passband. received signal.mp4
