b<>com *Wireless Library* [Polar FEC]

A 3GPP 5G-New Radio Compliant Polar-Code IP

Product presentation

b<>com *Wireless Library* [Polar FEC] is an encoder/decoder IP compliant with 3GPP NR specifications for 5G applications. The decoder implements a Successive Cancelation List (SCL) algorithm whose list size (L) is customizable to match different targets of BER performance and hardware sizes. The IP is wrapped in generic interfaces for easy integration into your product design.
