NTN L1 for 5G NR & 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).
