NTN PHY IP: 5G NR and NB-IoT
RF DSP’s 5G NR low PHY IP and DFE designs are optimized for NTN LEO requirements supporting:
- Large number of simultaneous beams and high subscriber density
- FR1 L-band and S-band, and FR2 Ka-band and Ku-band
- Real-time mapping of multiple carriers/data streams to beams
- Intelligent management of multiple simultaneous beams at the same frequency to maximize spectral efficiency
- Advanced Massive MIMO Hybrid Beamforming algorithms optimized for NTN channel models
- Digital Front-End (DFE) designs for NTN RF Frontend and beamforming configurations
- Reference design and API for PHY and DFE configuration and management Optimized for AMD Versal AI and Gen 4 RFSoC DFE chips (ZU67/65)
NB-IoT PHY IP & DFE Design
RF DSP’s NB-IoT PHY IP & DFE design core implements the PHY and DFE functions of NB-IoT UL and DL signals defined in the 3GPP Physical channels and modulation specification [TS 36.211 v17.3.0], with high performance and optimized blocks. The core can be configured for either Terrestrial Network (TN) or Non-Terrestrial Network (NTN).
