| Research Abstract |
We proceeded the theoretical studies on several open topics of modern information network systems, especially focused on problems of the interference channel and finite state channels such as the trapdoor channels. We gave transparent aspects on the difficulties contained in the problems. Moreover, we also concentrated the topics on LDPC codes based on the lattice, and proposed decoding algorithms using approximated Gaussian distributions for real-world applications.
