| Outline of Annual Research Achievements |
In the first year of this project, our project is progressing smoothly as we expected. Here we summarize our project in the past year as below: (1) the idea has been numerically approved through simulation; (2) the original idea of the project has been further extended for synthesizing high-order sub-carrier multiplexing (SCM) signal for directly-detection applications; (3) to successfully detect the synthesized high-order SCM signal, an algorithm has been specially developed to deal with the possible degradation induced by the imperfect power ratio and relative phase difference between input SCM subcarriers. These works are important for the next step experimental demonstrations.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
Our project is progressing smoothly as we expected. The main preparation for the project has been well done, including the numerical simulation and algorithm development.
|
| Strategy for Future Research Activity |
As we planned before, in the following years, we will start the experimental demonstration of the proposed system.
|
| Causes of Carryover |
The two co-investigator have remained budgets in the first fiscal year. The budget will be shifted to the next year for use.
