Performance of NMS decoding of SC polar codes based density evolution
Alaa A. Hasan, Ian Marsland · 2017
In this paper, the principle of density evolution (DE) combined with the normalized minimum-sum (NMS) decoding process is explored. It is demonstrated that with one properly chosen parameters for NMS algorithm, then almost the same behaviour of sum-product (SP) algorithm is achieved. As well, the complexity reduction is realized by calculating a linear function instead of nonlinear function. Simulation results show the validation of the suggested algorithm as expected.
