Building a 5G network - on the ground or in orbit - means solving some of the hardest problems in wireless communications. The physical layer is where those problems live, and where performance is won or lost. AccelerComm exists to solve them.

Our portfolio of 5G Layer 1 IP covers the full range of terrestrial and hybrid RAN requirements - LDPC channel coding, Polar decoding, and complete PxSCH processing chains, all proven in commercial deployments with leading chipmakers and network equipment vendors. Whether you need a complete physical layer or specific accelerator components, our IP integrates cleanly and performs at the absolute ceiling of the standard.

For satellite and NTNs, the challenges are fundamentally different - extreme Doppler, long propagation delays, power and thermal constraints that ground-based designs never face. Our NTN solutions are built specifically for these conditions, with IP already proven in orbit on commercial satellites and selected by partners including Lockheed Martin and Airbus UpNext.

Regenerative NTN

In a regenerative satellite architecture, 5G signals are processed fully on board — decoding, routing, and re-encoding without touching the ground. It delivers lower latency and greater network efficiency, but places extreme demands on the physical layer hardware that has to do it all in orbit.

AccelerComm AX-RG

AccelerComm's AX-RG solution delivers a complete, flight-proven 5G NR physical layer for regenerative NTN deployments, running on space-hardened silicon within the stringent SWaP constraints of an orbital payload.

TRANSPARENT/HYBRID NTN

In a transparent or hybrid architecture, the satellite relays the 5G signal without full on-board processing, placing greater demands on the ground-based physical layer to compensate for the channel impairments introduced by the link. AccelerComm's IP is optimised for exactly these conditions.

AccelerComm AX-TP

AccelerComm's AX-TP solution provides the high-performance physical layer signal processing that transparent and hybrid NTN architectures require — delivering the error correction and throughput performance that makes standards-based 5G viable across the full range of satellite link conditions.

Embedded FEC IP

Forward error correction is at the heart of every 5G physical layer. AccelerComm's embedded FEC IP delivers best-in-class LDPC and Polar coding performance in a form designed for clean integration into chipsets, FPGAs, and ASICs across terrestrial and NTN applications.

AccelerComm LDPC

AccelerComm's LDPC IP delivers the highest error correction performance available for 5G NR data channels, with configurable parallelism, full 3GPP compliance, and a complete encoding and decoding chain that includes rate matching and HARQ. Proven in production silicon across multiple chipmaker deployments.

AccelerComm POLAR

AccelerComm's Polar IP provides complete encoding and decoding for 5G NR control channels, using PC- and CRC-aided SCL decoding techniques to achieve best-in-class error correction performance within a 40% smaller footprint than competing solutions.

Lab-based NTN Evaluations

Testing 5G NTN systems in orbit is expensive and time-consuming. AccelerComm's lab-based evaluation solutions allow customers to validate physical layer performance under realistic NTN channel conditions on the ground - before committing to a flight programme.

AccelerComm EVK

AccelerComm's Evaluation Kit provides a complete, ready-to-run hardware and software environment for testing 5G NTN physical layer performance in the lab. Designed to replicate the channel conditions of LEO, MEO, and GEO orbits, the EVK gives programme teams the confidence they need before moving to flight hardware.

Our IP doesn't just perform in the lab. It performs in orbit.

AccelerComm's physical layer solutions are already flying on commercial satellites, proven in conditions that no terrestrial network ever faces. Customers building the next generation of satellite programmes are choosing IP that has already made it to space.
