- Add Channelizer class for wideband capture processing (2 MHz → 125 kHz) - FIR low-pass filter with scipy.firwin (or fallback windowed-sinc) - Proper decimation for anti-aliasing - Fix FrameSync preamble detection to accept any CFO - Real captures have significant carrier frequency offset - Preamble bins appear at arbitrary values, not just near 0 - Now accepts any strong signal as first preamble, validates consistency - Add decode_capture.py example script for processing raw BladeRF captures - PHYDecode verified to match existing lora_phy decoder output

"""gr-rylr998: GNU Radio OOT module for RYLR998 LoRa modems.
|
|
|
|
Provides complete TX/RX blocks for RYLR998 LoRa modems with support for
|
|
the reverse-engineered NETWORKID → sync word mapping.
|
|
|
|
Blocks:
|
|
- css_demod: CSS demodulator (FFT peak detection)
|
|
- css_mod: CSS modulator (chirp generation)
|
|
- frame_sync: Preamble + sync word detection
|
|
- frame_gen: Header + preamble + SFD generation
|
|
- phy_decode: Gray decode → deinterleave → Hamming → dewhiten
|
|
- phy_encode: Whiten → Hamming → interleave → Gray encode
|
|
|
|
Utilities:
|
|
- networkid: NETWORKID ↔ sync word conversion
