| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Because a wireless technology that can configure wide-area IoT systems with high data rates is required toward 6G, it is necessary to develop advanced wireless transmission schemes that achieve a data rate equivalent to conventional LTE-M and mMTC with better spectral efficiency. In this report, we propose an orthogonal frequency division multiplexing (OFDM) with symbol-edges truncating transmission (STT-OFDM) for spectral efficiency enhancement. In the proposed STT-OFDM scheme, only a part of the cyclic prefix (CP)-OFDM symbols, which is the legacy communication scheme adopted to 4G and 5G, is transmitted. On the receiver side, zeros are inserted where the no transmission took place at the transmitter side before a general OFDM demodulation is performed. The energy per one-symbol transmission is expected to be reduced by the proposed STT-OFDM. Computer simulation results show that the proposed STT-OFDM can improve the throughput of the CP-OFDM by about 1.5 times even in low SNR environments. | |
