AccelerComm's LDPC IP cores deliver flight-proven FEC performance for 5G and 6G NTN PHY designs. Built on advanced decoding algorithms developed from decades of academic research at the University of Southampton, they provide the error-correction performance that demanding satellite and terrestrial PHY workloads require.

AccelerComm LDPC provides licensable, 3GPP-compliant encoder and decoder IP cores optimised for terrestrial, transparent NTN, and regenerative satellite PHY architectures. Its high-throughput, low-latency design is FPGA- and ASIC-ready, with area-efficient implementations suited to SWaP-constrained satellite payloads and high-density ground infrastructure alike.

Already deployed in orbit on more than 200 commercial satellites, AccelerComm's LDPC IP brings a level of flight heritage that few physical layer vendors can offer. For programme teams designing 5G or 6G NTN systems where link efficiency and error-floor performance are critical, it provides a standards-based foundation that de-risks PHY development from the outset.

KEY BENEFITS OF ACCELERCOMM LDPC

01. Flight-proven FEC at commercial scale

AccelerComm's LDPC IP has been validated in orbit on more than 100 satellites — giving PHY design teams a proven, low-risk foundation rather than an unvalidated starting point.

02. Up to 10x performance improvement over software-based LDPC

Hardware-optimised IP cores deliver a step-change in throughput and power efficiency compared to software implementations, reducing cost-per-bit across both payload and ground deployments.

03. 1 dB uplink sensitivity gain

Advanced decoding techniques unlock a measurable link margin improvement, enabling higher throughput, smaller terminals, or extended coverage from the same infrastructure.

04. Ultra-low BLER — no error-rate floors

AccelerComm's algorithms eliminate the error-rate floors seen in conventional decoders, delivering consistently reliable performance across the full range of channel conditions.

AccelerComm LDPC IP is the FEC foundation for 5G and 6G PHY designs where performance at the standard's ceiling is not optional.

Backed by a portfolio of 55 international patents and proven across terrestrial chipmakers, satellite primes, and commercial constellation programmes, AccelerComm's LDPC IP integrates cleanly into existing FPGA and ASIC design flows. Its scalable architecture supports evolving 5G and NTN standards, making it a long-term investment for programmes already planning for 6G. AccelerComm's engineering team works alongside customers throughout integration — from initial evaluation through to production sign-off — ensuring that the performance gains demonstrated in simulation are fully realised in silicon and in orbit.
