| Outline of Final Research Achievements |
We proposed a signal processing technique to easily realize a wireless communication system which is required to suppress out-of-band emission strictly such as television white space radio communication systems and evaluated its effectiveness and feasibility. The proposed scheme is applicable to the discrete Fourier transform (DFT)-based multicarrier systems such as the orthogonal frequency division multiplexing (OFDM)-based systems which are currently widely used in wireless LAN, LTE, LTE-Advanced, etc. In the proposed scheme, a very long windowing transmission duration is applied to the wave-shaping with powerful error collection coding scheme such as turbo coding to suppress the out-of-band emission effectively with low-complexity.
