Path Splitting Selecting Strategy based on Search Set Successive Cancellation List (PSS-SS-SCL) Algorithm can effectively reduce the decoding complexity by reducing the number of unnecessary splits. In this paper, we reduces the number of bits in the critical set according to the depth of the Rate-1 node and set a decision threshold θ to reduce the complexity further and make the performance loss negligible. Simulation result shows that for L=2, P-PSS-SCL can achieve 35% reduction in complexity compared to PSS-SS-SCL decoding algorithm at Eb/N0=2.
