Fully Integrated PUSCH decoder for high performance 5G NR
PDSCH Encoder and PUSCH Decoder increase spectral efficiency and reduces latency for performance-critical 5G NR networks.

AccelerComm is driving 5G NR with cutting edge Physical Layer IP which increases spectral efficiency and reduces latency. A complete high-performance 5G NR PUSCH (Physical Uplink Shared Channel) Decoder and PDSCH (Physical Downlink Shared Channel) Encoder is available for maximising the efficacy of 5G radio networks.

Building on the company’s carrier-grade portfolio of channel coding and modulation/demodulation IP, this highly integrated product enables 5G base stations to benefit from AccelerComm’s proven best-in-class LDPC decoder performance, whilst minimising time to market.

“Spectrum is a scarce resource, and is the key asset owned by mobile operators, so it is critical that they maximize its use – every dB counts,” said Robert Barnes, VP Sales & Marketing of AccelerComm. “This product builds on the existing AccelerComm IP portfolio to enable operators to deliver on the high-performance, low-latency promise of 5G using their existing spectrum and cloud RAN infrastructure.”

The PUSCH Decoder integrates additional 3GPP physical layer functions together with its high-performance LDPC decoders, to createa 3GPP-compliant IP package that can be quickly integrated and optimized for use in custom silicon (ASIC) and programmable hardware (FPGA). The flexible architecture means that it can be customized depending on an operator’s service requirements, resulting in optimal performance, power, and silicon area, tailored to their specific needs.

This latest product from AccelerComm adds new blocks of IP to complete the link between the LDPC decoder and the MIMO detector:

  • gNodeB uplink stack (PUSCH Decoder) – LDPC decoder with transport block wrapper, polar decoder, demultiplexer, descrambler and QAM demodulator;
  • gNodeB downlink stack (PDSCH Encoder) – LDPC encoder with transport block wrapper, scrambler, and QAM modulator.

The specification is as defined in Sections 6.2 and 7.2 of the 3GPP document TS 38.212, as well as Sections,, and of TS 38.211.
