5GR - 5G Broadcast Receiver

A production desktop receiver for 5G Broadcast (3GPP FeMBMS / LTE-based terrestrial broadcast) with Release 19 support, including CAS muting and time and frequency interleaving (TFI).

Features

• Input from BladeRF, I/Q samples files and I/Q over UDP data. Support for Ettus/USRP coming soon.
  
• Channel bandwidths: 1.4, 3, 5, 6, 7, 8 and 10 MHz.
  
• Subcarrier spacings: 15 kHz, 7.5 kHz, 2.5 kHz, 1.25 kHz, and 0.37 kHz
  
• MCS: normal 0..28, higherOrder 0..27 (including 256QAM MO)
  
• System Information decoding: SIBs 1, 2, 12, 13, 15, 16 and MCCH.
  
• Reception of CB messages (CMAS)
  
• Integrated parsing of Service Announcements
  
• Decoding and playback of RTP (MPEG-TS) sessions, and HLS and DASH delivered via FLUTE/ALC.
  
• Full E-UTRA band table for Rel-19.
  
• Full CAS Muting support with DRX-like sleep up to n=16 (2.56s)
  
• TFI: Time and Frequency Interleaving
  

Live measurements

• RF front end — RSSI, peak, crest factor, noise floor, left and right
  spectrum shoulders, occupied bandwidth.
  
• Cell — RSRP, RSRQ, SNR, fine CFO, timing, PDSCH BLER (EMA), pre-FEC BER
  on CRC-OK transport blocks, channel impulse response with the CP boundary
  overlaid.
  
• MBSFN area / PMCH — per-area RSRP and SNR; per-PMCH EVM, BLER, and CIR.
  
• Per session — RTP packets, octets, lost, duplicated, reordered, access
  units, keyframes; FLUTE FEC scheme, redundancy, source / repair symbol
  counts, completed files.
  

The receiver tracks up to five candidate cells in parallel and weighs them
with a composite quality metric, so cell reselection happens automatically
when the strongest cell changes.
