| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we propose a transmission method to reduce a nonlinear distortion, which is a problem when a OFDM(Orthogonal Frequency Division Multiplexing) is used for RFID(Radio Frequency Identification) with a superregeneration method. The amplification characteristic in the superregeneration method has nonlinearity, various nonlinear component consequently occur when a multicarrier signal passes through it. For this problem, the OFDM-FSK(Frequency Shift Keying) which can reduce the number of carrier waves is effective and reduces the influence of the nonlinear distortion. However, a transmission characteristic deteriorates when the number of FSK increases in the OFDM-FSK. We therefore propose an adaptive OFDM-FSK to reduce the influence of the nonlinear distortion by using different multiple values of FSK. We show that a transmission characteristic can be largely improved by using the proposed method through some computer simulations. | |
