摘要：
The coexistence of broadband systems with currently deployed Professional Mobile Radio (PMR) communication systems like Public Protection and Disaster Relief (PPDR) has gained much deserved attention. In the recent literature, it has been suggested that LTE-like FBMC-OQAM system working on linear devices can coexist in PMR band, while conventional OFDM-based LTE system fails. When we take into account, the RF impairments in radio communication systems; it is inevitable to consider the non-linear nature of High Power Amplifiers (HPAs), as they add severe hindrance in this aspect. In this paper, we address this issue and show that LTE-like FBMC-OQAM system working on non-linear devices can still co-exist with PMR/PPDR systems, when suitable peak-to-average power ratio (PAPR) is applied.
