Abstract

A circular convolution-based filter bank multi-carrier system adopting quadrature amplitude modulation (CQAM-FBMC) that utilizes partial response signaling (PRS), referred to as the PRS-CQAM-FBMC system, is proposed and analyzed. The proposed PRS-CQAM-FBMC system has fully overlapped FBMC symbols without the time shifts and the transition time through the circular convolution filter banks in the time domain and the improved localization property by the PRS of the poorly localized QAM-FBMC symbols in the frequency domain. Therefore, the PRS-CQAM-FBMC system can achieve higher spectral efficiency than the conventional QAM-FBMC system in short-packet transmission scenarios. The analyses and simulation results show that the symbol error rate performances of the PRS-CQAM-FBMC system without cyclic prefix are robust in additive white Gaussian channels and multi-path fading channels. Moreover, the PRS-CQAM-FBMC system with the improved localization property by PRS can further provide enhanced spectral efficiency by more than 10%.
