cog-ha-matter required wifi-densepose-sensing-server with the `mqtt`
feature exposed, which crates.io 0.3.0 did not expose. Chain:
1. wifi-densepose-signal 0.3.0 -> 0.3.1 (already includes
EmbeddingHistory::{with_sketch,novelty} locally; needed
republish so sensing-server-0.3.1 can compile against it).
2. wifi-densepose-sensing-server 0.3.0 -> 0.3.1 (now exposes
the `mqtt` feature, sensing-server bin links against
signal-0.3.1 cleanly).
3. cog-ha-matter sensing-server dep bumped to ^0.3.1; publish=false
dropped. cog-ha-matter@0.3.0 published.
Both signal and sensing-server published with --no-verify; cargo's
verification step fails on Windows because openblas-src requires
vcpkg (the source itself builds fine in the workspace and on Linux).

wifi-densepose-signal
State-of-the-art WiFi CSI signal processing for human pose estimation.
Overview
wifi-densepose-signal implements six peer-reviewed signal processing algorithms that extract
human motion features from raw WiFi Channel State Information (CSI). Each algorithm is traced
back to its original publication and integrated with the
ruvector family of crates for high-performance
graph and attention operations.
Algorithms
| Algorithm | Module | Reference |
|---|---|---|
| Conjugate Multiplication | csi_ratio |
SpotFi, SIGCOMM 2015 |
| Hampel Filter | hampel |
WiGest, 2015 |
| Fresnel Zone Model | fresnel |
FarSense, MobiCom 2019 |
| CSI Spectrogram | spectrogram |
Common in WiFi sensing literature since 2018 |
| Subcarrier Selection | subcarrier_selection |
WiDance, MobiCom 2017 |
| Body Velocity Profile (BVP) | bvp |
Widar 3.0, MobiSys 2019 |
Features
- CSI preprocessing -- Noise removal, windowing, normalization via
CsiProcessor. - Phase sanitization -- Unwrapping, outlier removal, and smoothing via
PhaseSanitizer. - Feature extraction -- Amplitude, phase, correlation, Doppler, and PSD features.
- Motion detection -- Human presence detection with confidence scoring via
MotionDetector. - ruvector integration -- Graph min-cut (person matching), attention mechanisms (antenna and spatial attention), and sparse solvers (subcarrier interpolation).
Quick Start
use wifi_densepose_signal::{
CsiProcessor, CsiProcessorConfig,
PhaseSanitizer, PhaseSanitizerConfig,
MotionDetector,
};
// Configure and create a CSI processor
let config = CsiProcessorConfig::builder()
.sampling_rate(1000.0)
.window_size(256)
.overlap(0.5)
.noise_threshold(-30.0)
.build();
let processor = CsiProcessor::new(config);
