3gpp IP

The Helion 3GPP KASUMI cores perform the f8 confidentiality and f9 integrity algorithms required to provide data security within the GSM/EDGE and UMTS mobile communication standards.
Both algorithms are based on the KASUMI 64-bit block cipher which uses a 128-bit key. The KASUMI algorithm was designed by the Security Algorithms Group of Experts (SAGE) within ETSI, and is an optimised version of the MISTY1 block cipher originally developed by Mitsubushi Electric Corporation of Japan. Within ETSI, the f8 and f9 algorithms are now known as UEA1 and UIA1 respectively.

The PDSCH Encoder and PUSCH Decoder products simplify the creation of high performance 5G NR implementations.
PDSCH Encoder features the new QAM mapper and Scrambler functionality. These are integrated with LDPC encoder chain and transport block chain components.
PDSCH encoder has a configurable IQ parallelism for improved performance per clock.
The functions included are CRC, Segmentation, LDPC encode, Rate matching, Integrated HARQ, Concatenation, Scrambling and Modulation.

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.
