Students learn fundamental knowledge from information theory.
They can assume the basic models of information, and learn several theories such as various codings (Prefix coding, Huffman coding, Elias coding, Ziv-Lempel coding, Run Length coding), the fundamental theorem of channel capacity, forward error correction (Linear Block code, cyclic code, convolutional code, LDPC code), and basic encryption (Public key).
Students can gain an understanding of and acquire knowledge of fundamental theories of information coding, compression, channel capacity, various forward error corrections, and encryption.

At the beginning of each class, answers to the exercises from the last class are explained. Next, the instructor lectures on the material for that class. Towards the end of the class, students are given time for exercise problems.
Before class, the texts are uploaded to the OCW-i web site. Students should download them, and briefly read them. After class, they are requested to read the texts for understanding the class material.
