DSP & Math IP

The patented polar encoding and decoding IP for the 3GPP New Radio uplink and downlink includes the entire processing chain, to provide quick and easy integration and minimize the amount of extra work needed.
The polar core uses PC- and CRC-aided SCL polar decoding techniques, in order to achieve compromise-free error correction performance.

The LDPC decoder product suite has been specifically designed as flexible IP to address the unique challenges of 5G NR across all use cases covered by the current standards, deliver market leading performance and efficiency, and be easily integrated into designs.

So_ip_idt core can be used create a decision tree directly in hardware. It can create DTs with univarite, multivariate and non-linear tests.
Creating DTs directly in hardware results in the significant increase of DT inference speed, compared with the traditional software-based approach.

A highly configurable DVB-T demodulator core suitable for a wide-range of applications included test, measurement and broadcast montioring equipment.
The core provides the DVB-T(H) extensions which when combined with the superior performance offered by our inter-carrier-interferance cancellation algorithm make this core ideally suited for mobile environments

The CMS0021 Single-channel Cable Modulator encodes a transport stream for J83 or DVB-C.
The resulting QAM-symbols are filtered and up-converted for output to the radio interface as a single I/Q sample stream for translation to the final RF frequency.

The CMS0024 Multi-channel Cable Modulator encodes up to four separate transport streams for J83 or DVB-C.
The resulting QAM symbols are filtered and up-converted, each channel to its own frequency division multiplex (FDM) sub channel.
The IF channels are then combined output to the radio interface as a single I/Q sample stream for translation to the final RF frequency.

The CMS0022 DVB-C/J.83 Cable Demodulator is a 4th generation design that exploits the vendor’s experience of QAM and OFDM systems for broadband terrestrial, satellite and cable modems.
The core forms an integrated cable demodulator solution comprising of the Universal QAM Demodulator(CMS0006) and J.83abc/DVB-C Cable FEC Decoder(CMS0018) cores.

The CMS0018 J.83abc/DVB-C Cable FEC Decoder combines all of the channel coding and Forward Error Correction functions specified by DVB-C and by J83 – Annexes A B and C

The CMS0018 includes functions for QAM constellation slicing, trellis decoding, de-framing, de-scrambling, de-interleaving, and Reed-Solomon decoding.

The CMS0044 J.83abc/DVB-C Cable FEC Encoder combines all of the channel coding and Forward Error Correction functions specified by DVB-C and by J83 Annexes A B and C.
It is designed to interface to external modulators or advanced upconverting DACs such as the Analog Devices AD9789.

The CMS0035 DVB-Satellite Modulator is an integrated core featuring our DVB-S/-DSNG modulator (CMS0010) and DVB-S2/-S2X modulator (CMS0025) cores. The CMS0035 core provides all the functionality required to address the requirements of the ETSI forward-link satellite Standards EN 300 421 (DVB-S), EN 301 210 (DSNG), EN 302 307-1 (DVB-S2) and EN 302 307-2 (DVB S2X), with additional support for DVB-S2X VLSNR operation
The core can operate in a constant coding-and-modulation (CCM) mode for all Standards and in the enhanced variable-coding-and modulation (VCM) and adaptive-coding-and modulation (ACM) modes provided by DVB-S2 and DVB-S2X.
