Patent number: 11063606Abstract: A successive cancellation list-based decoder and a decoding method thereof are provided. In the method, an error check is performed on a set of data bits. A data unit includes the set of the data bits and at least one first check bit. Part of the set of data bits are considered as at least one second check bit.
