AccelerComm: Implementation challenges of polar codes

March 07, 2018 // By Professor Robert Maunder
This white paper discusses the selection of polar codes in the 5G New Radio standard and provides tutorials on the polar encoding and decoding processes, paying particular attention to the Successive Cancellation (SC) and Successive Cancellation List (SCL) decoding algorithms. The paper also discusses the challenges associated with the hardware implementation of polar encoders and decoders, noting that these challenges are particularly great in the case of the polar decoder, since its complexity is orders of magnitude greater than that of the polar encoder.
