| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Channel compensation often employs pre-equalization and/or adaptive diversity schemes. Such techniques require channel prediction because a channel changes in time. Previously, we reported a channel prediction technique to increase the accuracy by focusing on polarization state and combine multiple polarization components estimated in the nearest past signal set. However, when the polarization state is changing as well, this method fails. In this paper, we propose a channel prediction combined with polarization prediction on the unity-radius Poincare sphere by using a quaternion neural network. We demonstrate a higher accuracy in channel prediction, resulting in a low bit error rate. | |
