Communications and DSP
Move modulation, sampling, spectra, BER and fixed-point error from equations into reference models and observable data.
About
I focus on communications and DSP, FPGA and embedded systems, and the software tools that support verification and delivery. This site records how a problem is defined, implemented, tested and documented—not only the final result.
Focus
These are not isolated labels. Together they form a complete path from signals and algorithms to hardware behavior and a reproducible handoff.
Move modulation, sampling, spectra, BER and fixed-point error from equations into reference models and observable data.
Use RTL, testbenches, timing constraints and board interfaces to build hardware that can be evaluated, debugged and integrated.
Use scripts, databases, containers and technical documentation for reference checks, visualization, reproducibility and publication.
Project evidence
Each project record keeps its current verification level, key implementation details, reproduction path and unfinished work visible.
Combines multi-waveform DDS, PCF8591 AD/DA, sample statistics and seven-segment display output.
View project recordCovers PRBS, Gray mapping, a phase channel, hard decisions, BER and a host-side constellation plot.
View project recordConnects OpenCV detection, calibration, kinematics, a serial protocol and FreeRTOS control.
View project recordUses Python, SQLite and Docker for document upload, local retrieval and optional AI answers.
View project recordEvidence boundary
Simulation, a successful build, timing closure and physical board verification are different claims. Each page identifies the evidence that exists; hardware acceptance that has not happened remains an explicit limitation instead of being presented as a result.
