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).
