In this Letter, a product concatenation scheme of systematic polar codes with irregular low-density parity check (LDPC) codes is proposed. The proposed scheme may take advantage of the good error-correction capability of irregular LDPC codes and superior error floor performance of polar codes. The joint belief propagation algorithm is employed, where scaling factors are introduced to manipulate the belief messages exchanged between constituent decoders, such that a fast convergence and a low BER performance may be achieved. Simulations are presented to validate its effectiveness.
