Abstract
This paper proposes a simplified control unit for fast simplified successive cancellation (FSSC)-based decoders. Specifically, this paper presents detailed hardware architectures for the simplified stage and operation decision modules based on the one-hot encoding of control signals. In addition, the proposed simplified control unit is applied to an FSSC decoder and it is compared with state-of-the-art polar decoders. The proposed control unit requires approximately 71% less normalized area than the existing finite-state machine-based control unit. Furthermore, the proposed FSSC decoder for the control unit improves the normalized area efficiency by up to 63% compared to conventional FSSC-based decoders.
