Hybrid Non-Binary Repeated Polar Codes

Concatenating the state-of-the-art codes at moderate rates with repetition has emerged as a practical solution deployed in various standards for ultra-low-power devices such Internet-of-Things (IoT) networks. In this paper, we propose novel concatenation mechanism applications which need to operate very low signal-to-noise ratio (SNR) regime. proposed scheme, outer code is hybrid polar constructed two stages, one binary kernel and another also but applied over extension field. The inner non-binary multiplicative code. This particular structure inherits low-complexity decoding structures of while enabling an scheme. scheme done using cyclic redundancy check (CRC) aided successive cancellation list (SCL) decoder additive white Gaussian noise (AWGN) Rayleigh fading channels. Simulation results demonstrate that repeated provides performance gain compared polar-repetition comparable complexity.
