Simplified sequence repetition nodes-based fast successive cancellation decoding algorithm for polar code
In order to reduce the decoding latency of the successive cancellation (SC) decoding algorithm further, a kind of fast SC decoding algorithm based on simplified sequence repetition (SR) nodes, namely simplified sequence repetition node-based fast SC (SSRFSC), was proposed to optimize decoding latenc...

| description | In order to reduce the decoding latency of the successive cancellation (SC) decoding algorithm further, a kind of fast SC decoding algorithm based on simplified sequence repetition (SR) nodes, namely simplified sequence repetition node-based fast SC (SSRFSC), was proposed to optimize decoding latency issues of SC decoding algorithm.Different types of extended class of generalized parity-check (EG-PC) nodes were decomposed, merged and simplified based on the type of SR source node and decoding complexity, and Rate-C node was trimmed using fast simplified successive cancellation (Fast-SSC) decoding.Experimental results show that the decoding latency of the proposed algorithm can be reduced by up to 28% compared to the latest simplified sequence repetition (SRFSC) decoding algorithm when achieving similar decoding performance (approximately 0.1dB performance loss at frame error rate of 10<sup>-3</sup>).Moreover, compared to the Fast-SSC decoding algorithm, the decoding latency of proposed algorithm can be reduced by up to 49%. |
