Matlab simulations of the encoder and Successive Cancellation List (SCL) decoder for the New Radio polar code from 3GPP Release 15, as defined in TS38.212 V15.2.0 and used in the Public Broadcast Channel (PBCH), Physical Downlink Control Channel (PDCCH) and Physical Uplink Control Channel (PUCCH).
This code is intended to provide a reference model for the standard and has been written with a focus on correctness, rather than on simulation speed. This code is also intended to provide a platform for research on enhancements to the New Radio polar code. This motivates the inclusion of the custom1_encoder and custom1_decoder, alongside encoders and decoders for the New Radio PBCH, PDCCH and PUCCH channels. In particular, custom1_encoder and custom1_decoder adapt the New Radio polar code for general purpose applications, enabling support for arbitrarily-high information block lengths A. By contrast, the longest block lengths supported in the New Radio PBCH, PDCCH and PUCCH channels are 32, 140 and 1706 bits, respectively.
