=== Week 1 (5/27 - 5/29): ===
**Slides:** [https://docs.google.com/presentation/d/1hvr30TzM7EJ0IWJ53jkBN7Zxs11MewyA62KL5Y6unOM/edit?usp=drive_link Week 1 Presentation] 

**Progress:** 
- Conducted literature review on relevant research papers
 1. [https://www.winlab.rutgers.edu/~narayan/PAPERS/5GWF_Conf_Paper_Final.pdf Modeling the Impact of 5G Leakage on Weather Prediction]
 2. [https://ieeexplore.ieee.org/document/10195226 Will Emerging Millimeter-Wave Cellular Networks Cause Harmful Interference to Weather Satellites?] 
 3. [https://ieeexplore.ieee.org/document/10632798 How Does the Growth of 5G mmWave Deployment Affect the Accuracy of Numerical Weather Forecasting?]  
- Understood the high level idea of what **Radio Frequency Interference(RFI)** and **frequency allocations** are 
- Explored how ML can be implemented to minimize the interference between satellite and 5G in different spectrums

=== Week 2 (6/2 - 6/5): ===
**Slides:** [https://docs.google.com/presentation/d/1PqrNeu_GJZgtgby3EKuNGA3qdGhwVvmpP4UPYoz4LJg/edit?usp=drive_link Week 2 Presentation]

**Progress:** 
- Familiar with the pros and cons of the different approaches to beam-forming, especially the benefits of ML application
- Read research papers related to a physical-testbed-generated RFI dataset, and got familiar with the data generation process: 
 1. [http://ieeexplore.ieee.org/document/10663400 A Physical Testbed and Open Dataset for Passive Sensing and Wireless Communication Spectrum Coexistence]
 2. [https://ieeexplore.ieee.org/document/10318952 Microwave Radiometer Calibration Using Deep Learning With Reduced Reference Information and 2-D Spectral Features]
 3. [https://ieeexplore.ieee.org/document/9954900 Radio Frequency Interference Detection for SMAP Radiometer Using Convolutional Neural Networks]

=== Week 3 (6/9 - 6/12): ===
**Slides:** [https://docs.google.com/presentation/d/159CiF4dxDeX_jZNkPRP5pg5ZLAY3BmdEWMqAPmpjnsc/edit?usp=drive_link Week 3 Presentation]

**Progress:** 
- Began to process data with Numpy and h5py, generating Power Spectral Density (PSD) graphs and spectrograms from L1A data 
- Utilized the radiometer's ability to interpret all received power as thermal radiation to quantify RFI by detecting abnormal temperature increases
- Saved plotted graphs into a 2D Numpy array for future model training use (4 columns: RFI Scenario | PSD | Spectrogram | Temp Difference)
