  In a recent work we proposed a new radio access technique based on filter
bank multi-carrier (FBMC) modulation using two orthogonal polarizations:
dual-polarization FBMC (DP-FBMC). We showed that with good cross-polarization
discrimination (XPD), DP-FBMC solves the intrinsic imaginary interference
shortcoming of FBMC without extra processing. DP-FBMC also has other
interesting advantages over cyclic prefix orthogonal frequency-division
multiplexing (CP-OFDM) and FBMC such as more robustness in dispersive channels,
and it is also more robust to receiver carrier frequency offset (CFO) and
timing offset (TO). In this paper we analyze the peak to average power ratio
(PAPR) of DP-FBMC and compare PAPR simulation results with that of conventional
FBMC, for different prototype filters and overlapping factors. According to the
analysis and results, with a proper choice of prototype filter, DP-FBMC has
comparable PAPR to FBMC.
