 note = {P(論文), Previously, the authors proposed three-frequency commutation FSK signaling to improve performance of high-speed digital mobile radio system in severe multipath fading environment. However, this strategy expanded excess bandwidth and caused extra interferences. It exhibited poor performance particularly in the practical modulation index region. In this paper, we propose the new commutation signaling strategy named On-Off Keyed FSK (OOKFSK) and theoretically analyze the BER performance of this signaling method. This method transmits no signal instead of transmitting the third-frequency signal in the three-frequency commutation FSK. The numerical results show that the OOKFSK signaling outperforms the three-frequency commutation FSK signaling for practical low modulation indices.},
