== Project Objective ==

The goal for this project is to create an.

Several objectives:

* Using nodes in COSMOS/ORBIT testbed to transmit refence signals
* Collect data from the transmission process with the portable SDRs
* Use both traditional and AI/ML analysis for channel characterization (including occupancy) 

Reading material:

Planned to meet weekly at 12pm on Tuesday and 2pm on Thursday

== Week 1 Activities ==
* Get familiar with ORBIT
* Research on software defined radio (SDR)

== Week 2 Activities ==
* Ran basic experiments on ORBIT testbed
* Studied more about SDRs and Channel Monitoring 
* Learnt basics of Ubuntu

== Week 3 Activities ==
* Researched about different Sandboxes in ORBIT
* Perform more experiments with SDRs
* Studied about different hardwares in ORBIT
== Week 4 Activities ==
* In USRP capture the waveforms and plot it
* In sandbox, used 1 node as transmitter and other as receiver and observed the transmission process
== Week 5 Activities ==
* Used 2 transmitter and 2 receiver to send data across each other and plot the wavefroms
* Conducted specturm sensing using USRP2

== Week 6 Activities ==
* Tried resolving the FPGA and GNU errors 
* Looked into different technical papers for ML approach used for spectrum sensing

== Week 7 Activities ==
* Successfully conducted experiment using GNU radio and tried plotting the spectrum using GNU companion
* Conducted specturm sensing using USRP X310 and WISERD

== Week 8 Activities ==
* Successfully collected sample data from the spectrum sensing experiment using WISERD
* Still trying to resolve the errors faced using GNU companion 
* Looked into few ML algorithms and try to finalize one by this weekend
