Product codes are preferred in high data rate wireless communication systems to achieve good error performance. However, to conceive a proper decoding method, which can correct all the potential errors pattern that within the half of the code distance for the product code, is not easy. In this paper, an improved decoding method of hamming product code has proposed. The proposed ...

With the rapid development of artificial intelligence technology, many intelligent tutoring systems (ITS) based on artificial intelligence technology have been developed. The most basic 2 functions of the ITS are: 1. ability to convert user answers described in natural language into fragment of knowledge base of ITS; 2. knowledge-based representation rules automatically verify ...
