| Outline of Final Research Achievements |
This research has proposed a novel method to reduce unwanted emissions into adjacent bands in OFDM (Orthogonal Frequency Division Multiplexing) system. This method is derived from a conventional method called as N-continuous OFDM that is a kind of precoding methods and does not use windowing functions.
From the experimental results of the research, the power spectral density and symbol error rate characteristics of the proposed method equal to or greater than those of the conventional method were obtained without using the iterative algorithm. The proposed method was confirmed to be particularly effective on a system with a small number of subcarriers.
