FIR Filter Design/Implementation

Sat, 01 Aug 2026 00:00:00 +0000

Overview #

Designing an FIR Filter in Matlab and implementing in C++ and VHDL to perform optimization. The filter parameters were:

Sampling Rate: 100 MHz
Passband: 10 MHz
Stopband: 15 MHz

Theoretical Design #

The filter was first designed in matlab to determine the minimum amount of taps, and to find the corresponding FIR coefficients.

Wifi Deauthentication Attack Detection/Localization

Mon, 10 Nov 2025 00:00:00 +0000

Overview #

Along with with W. Schageman, developed an intrusion detection system to detect and triangulate the source of WiFi jamming via deauthentication attacks, common in network disruptions. ESP32(s) scan for deauth/dissoc packets in promiscuous mode, relaying alerts to a Raspberry Pi server for logging and analysis. Use Flipper Zero (with WiFi module/ESP32 marauder) to simulate deauthentication attacks in a lab environment. RSSI localization done via least squares multilateration.
