Query: Neural Dynamic Successive Cancellation Flip Decoding of Polar Codes   Dynamic successive cancellation flip (DSCF) decoding of polar codes is a
powerful algorithm that can achieve the error correction performance of
successive cancellation list (SCL) decoding, with a complexity that is close to
that of successive cancellation (SC) decoding at practical signal-to-noise
ratio (SNR) regimes. However, DSCF decoding requires costly transcendental
computations which adversely affect its implementation complexity. In this
paper, we first show that a direct application of common approximation schemes
on the conventional DSCF decoding results in significant error-correction
performance loss. We then introduce a training parameter and propose an
approximation scheme which completely removes the need to perform
transcendental computations in DSCF decoding, with almost no error-correction
performance degradation.
