Other/Summer/2024/ml5G
v14 v15 7 7 8 8 Reviewed several papers to gain insights into the current state of 5G networks and the interference mitigation techniques used across different frequency ranges.\\ 9 10 Familiarized ourselves with the task of our research: 11 We will be emulating 5G Base Stations and other terrestrial network receivers on the FR3 spectrum. Using SDRs (software-defined radios) on the COSMOS testbed. We can simulate certain scenarios regarding interference directly through a software interface and generate Signal to Interference and Noise Ratio (SINR) data to train machine-learning models to help mitigate interference. \\ 12 9 13 10 14 … … 22 26 Analyzed graphs that demonstrated the model's ability to learn from domain-invariant features.\\ 23 27 28 Reviewed Fourier analysis. \\ 29 30 Researched and analyzed Orthogonal Frequency Division Multiplexing (OFDM) signals to understand what we will be using to simulate 5G base stations. \\ 31 32 Designed a draft of an OFDM signal transmitter and receiver on GNU radio. \\ 33 24 34 25 35 \\ … … 35 45 Additionally, we explored how Dynamic Exclusion Zones apply to our mitigation objective. We weighed various approaches, debating whether the satellite receiver should autonomously localize interference sources or instead initiate a centralized algorithm for optimizing resource allocation.\\ 36 46 47 Explored the amarisoft stack and instantiated UEs to send arbitrary data packets. Successfully received those data packets. \\ 48 49 Examined a QPSK transmitter and receiver implementation. Analyzed all of the blocks used, to better understand the GnuRadio software. \\ 50 51 Began researching possible ways to detect signals and perform energy spectrum sensing. \\ 52 53 37 54 \\ 38 55 \\ … … 41 58 42 59 **Week 4 (6/17 - 6/20)** 60 61 Designed an SNR implementation for a generic FM transmitter. \\ 62 63 Finished designing the OFDM transmitter. \\ 64 65 Began fine-tuning the SNR implementation for OFDM transmissions. \\ 43 66 44 67 Emulated a DVB Satellite Transmitter in GNU Radio for the ORBIT Sandbox 1 - ran into some issues with existing implementations. … … 70 93 **Week 5 (6/24 - 6/27)** 71 94 95 96 Fine-tuned SNR to work with OFDM transmission \\ 97 98 Troubleshooted issues with the signal transmission through signal analysis with Phosphor. \\ 99 100 Began fine-tuning the SNR model to be working with the DBS transmission. 72 101 Developed and validated our SNR Sensor. The sensor effectively differentiates the original signal from noise, allowing for accurate SNR value calculations. To ensure the sensor's accuracy, we also used FOSPHOR to verify its performance, which alleviated our initial skepticism about the readings. Now we have to test it for our 3 experiments. 73 102 … … 93 122 Worked on scaling the SB2 Satellite Experiment up to the full Network Coexistence experiment on the ORBIT Grid. Matched the transmitter/receiver components to specific nodes. Debugged so that the nodes communicate with the on-site SDR devices. 94 123 124 Fine-tuned SNR to work with DBS transmission 95 125 126 Researched energy detection for SINR and possible GnuRadio implementations 127 128 Explored pilot-based OFDM SNR implementations 129 130 131
