+**WINLAB Summer Internship 2025**\\

+**Advisors:** Minsung Kim, Byungjun Kim
+
+== Project Objective
+
+The project will explore non-traditional computing methods for “Non-Orthogonal Medium Access-based Multiple-Input Multiple-Output” (NOMA-MIMO) wireless systems. Both MIMO and NOMA are considered among the most promising techniques to increase wireless capacity by scaling up the number of serviced devices at a time. However, to do so, they require much more computationally demanding processing at the receiver. A proposed solution is to reduce MIMO Maximum Likelihood Detection (MLD) to Quadratic Unconstrained Binary Optimization(QUBO), which resembles a Hamiltonian. We, then, convert QUBO into the Ising form under the Ising model, and use an Ising solver for the best Ising configurations. Finally, the best candidate will be mapped to MIMO Detected Bits.

+Over the summer, our team split into three groups to handle ...

+[https://docs.google.com/presentation/d/1yszAsj4qtqIHxvnbbeH1iDK50w9gC9EfXaJ5a0F07Ok/edit?usp=sharing Week 1 Wifi Based Detection Presentation]\\
+
+**Progress**: 
+- Researched Wifi-Fingerprinting and Human Adversarial Attack, and continued Integer optimization (Brian add here)
+
+
+==== WEEK TWO ====
+[https://link.to/week1_presentation Week 2 LDPC Presentation]\\
+[https://docs.google.com/presentation/d/1wHkZaah4bzEVJw7aZy4nscwAhSbyrr3xdgP4zhrRWTQ/edit?usp=sharing Week 2 Wifi Based Detection Presentation]\\
+
+**Progress**: 
+- Followed tutorial to rebuild a Wifi Fingerprinter for bit similar devices; used a Convolutional Neural Network for this
+- Edited the quadratic unconstrained binary optimization (QUBO) into a discrete solver using integer variables
+
+
+
+==== WEEK THREE ====

+[https://docs.google.com/presentation/d/1KkJF41sTUOw1vTagcLtjcmPIHCT2CmN5Yf8PfqvgCPo/edit?usp=drive_link Week 3 Wifi Based Detection Presentation]\\
+
+**Progress**: 
+- Fine-tuned and debugged the integer solver to correctly calculate the problem's energy
+- Familiarized with Orbit and ILabs to run CNN training
+
+
+==== WEEK FOUR ====

+[https://docs.google.com/presentation/d/1g-Zx8VQT5Coe2JyCAi3YAC7bfodBXoS4twaFKOZnDf4/edit?usp=drive_link Week 4 Wifi Based Detection Presentation]\\
+
+**Progress**: 
+- Began looking at Packet Carrier Frequency Offset(CFO) correction and Channel Estimation in MATLAB; Investigating UHD integration and construction of GNURadion Out-Of-Tree (OOT) custom C++/Python blocks
+- 
+
+
+==== WEEK FIVE ====
+[https://docs.google.com/presentation/d/1uUAVkGaK0YJtS1yFOWztQ9PL8ahJbn5fscuE0OxIlIg/edit?usp=sharing Week 5 LDPC]\\
+[https://docs.google.com/presentation/d/1QkA0YLWgsVQexPdltYdYLhg0rnUe921NqkisPEbGjfU/edit?usp=drive_link Week 5 Wifi Based Detection Presentation]\\
+
+**Progress**: 
+- Ran into difficulties with Packet CFO correction, achieved a 37.5-50% channel estimation. Also, due to the ceiling nodes having no central node for synchronization, we were faced with distributed systems communication issues. This led to a shift from MIMO rack to MIMO rack transmission and receiving. We began investigating FlexCore and Multisphere detection as alternative classical parallelized detectors. 
+
+==== WEEK SIX ====

+
+**Progress**: 
+- Began software-based implementation of FlexCore and continued GNURadio setup verification for MIMO rack to MIMO rack transmission
+

+
+**Progress**: 
+- LDPC: Used Bayesian optimization to initially tune, saw results, and then included more parameters that may be having an impact. Did research into how the model works and what parameters would have the most impact.
