    41 //Progress: //Explored the accuracy of the receiver while changing the power transmission, frequency, and distance between the SDR and signal generator. Learned about matched filters and how to [https://www.telecom.tuc.gr/~aggelos/files/TCOM2014.pdf implement them into the receiver]. Despite a frequency measurement error, we implemented logging into GNURadio using a file sink.

    4343\\Using the TI Launchpad Microcontroller we were able to implement FSK. also created a block diagram to illustrate how both the transmitter and receiver should work together to send information about a plant's temperature.\\

    5050//Progress: //This week, we received three different kinds of thermistors. We were able to implement a backscattered signal that encoded the information from the ADC (using a potentiometer). We are now investigating ways of measuring values from the thermistors, mainly considering a Wheatstone bridge.

     51//We also worked on the receiver, changing from GNURadio to MATLAB. This has so far shown to work extremely well and much better than GNURadio. We are able to receive the backscattered signal. However there are still some variances in the received signal we have to account for.
