Performance comparison of systematic polar code and non-systematic polar code

Tongxin xuebao, 2019
Polar code in channel coding schemes is a research hotspot in 5G communication field.Polar code is susceptible to error propagation under successive cancellation decoding,and the performance of the code at short and medium block lengths is not ideal.For ...

On the Concatenations of Polar Codes and Non-Binary LDPC Codes

IEEE Access, 2018
An interleaved concatenation scheme of polar codes with non-binary low-density parity check (NBLDPC) codes is proposed in this paper to improve the error-correcting performance of polar codes with finite code length. The information blocks of inner polar

Adaptive Quantization of the Polar Successive Cancellation Decoder

, 2019
Polar codes and its implementation challenges are an active study field since [1]. SC decoding algorithm is the well known polar decoding algortihm described in [1]. The chip area of the SC decoder is dominated by memory and register chains in the deeply-pipelined architecture [2].
