| Abstract |
Design of LDPC decoder depends on its check matrix. Since there exist a lot of check matrices with various sizes, it is not feasible to design a dedicated LDPC decoder for each check matrix. This work aims to make a versatile design framework to generate an LDPC decoder for each given check matrix. We consider a method to reduce the circuit area, focusing on the feature of the check matrix of 5G. In this paper, we present evaluation results of our framework, including gate count evaluations. We evaluated circuit areas of the decoders conforming to 5G. In the case of a check matrix where the number of information bits is about 120, the number of gates is about 3.7 M gates. |
