Quadrature Dev

Research and Development for digital signal processing, machine learning, and data science applied to communications, radio astronomy, and spectrum agility

Interests

Quadrature Dev is interested in the intersection of digital signal processing and data science, especially applied to problems with radio and wireless communications. We are interested in open source and have experience with PyTorch, GNU Radio, and accelerated instruction sets like SSE, AVX, NEON, and CUDA for GPUs.

Skills

Quadrature Dev has specialty in software development in C, C++, python, rust, and julia. We have targetted specialized instruction sets including CUDA for NVIDIA GPUs; SSE, AVX, AVX2, AVX512 for x86_64, NEON for ARM. We're familiar working around low-probability of intercept and detection waveforms and signal detectors including feature analysis and machine-learning methods. We have also contributed to full software modems for various waveforms and are comfortable with profiling tools for software optimization.

Services

Quadrature Dev is interested in developing software defined radios and novel applications of radio processing that leverages GPUs. We're available for contract development. Contact .

About

Quadrature Dev is the contracting/consulting entity for Nathan West. I have worked on projects for LPI/LPD signals analysis, machine learning and AI based spectrum awareness and agility, custom software modems for standard waveforms as well as AI-native communications, and search pipelines for doppler drifting signals in radio astronomy data for SETI. I have contributed to open-source software as (former) maintainer of VOLK and contributed to release management for GNU Radio. I am not currently accepting contract work, but have a set of technical hobby projects I keep up on the side. If you have an interesting project and want to discuss feel free to reach out to exchange ideas.
