“…hence the temporal symbol interval is T0 = 512/10 7 = 51.2 µs. As mentioned in [13], the mean RMS-DS values for pedestrian and vehicular A channels are 46 and 370 ns, respectively. For channel models we chose pedestrian and vehicular channels A from ITU-R recommendation M.1225 [10].…”

“…For Structure I, as long as we can share the same IFFT/FFT at every symbol period and polarization we obtain the same complexity and equipment as conventional FBMC. In this paper we focus on Structure I in simulations and analysis; more results and analysis are provided in [13]. For DP-FBMC systems, as long as the channel equalization process is being done separately on both polarizations, the equalization complexity is higher than for conventional FBMC, and as will be shown, this is the cost for better performance.…”

In this paper we describe the overall idea and results of a recently proposed radio access technique based on filter bank multicarrier (FBMC) communication system using two orthogonal polarizations: dual-polarization FBMC (DP-FBMC). Using this system we can alleviate the intrinsic interference problem in FBMC systems. This enables use of all the multicarrier techniques used in cyclic-prefix orthogonal frequency-division multiplexing (CP-OFDM) systems for channel equalization, multiple-input/multiple-output (MIMO) processing, etc., without using the extra processing required for conventional FBMC. DP-FBMC also provides other interesting advantages over CP-OFDM and FBMC such as more robustness in multipath fading channels, and more robustness to receiver carrier frequency offset (CFO) and timing offset (TO). For DP-FBMC we propose three different structures based on different multiplexing techniques in time, frequency, and polarization. We will show that one of these structures has exactly the same system complexity and equipment as conventional FBMC. In our simulation results DP-FBMC has better bit error ratio (BER) performance in dispersive channels. Based on these results, DP-FBMC has potential as a promising candidate for future wireless communication systems.

“…DP-FBMC Structure I has similar computational complexity and requires the same equipment and space as conventional FBMC. In [1] via simulation results we showed that in practical cross-polarization discrimination (XPD) conditions in different channel environments the proposed DP-FBMC has similar bit error ratio (BER) performance comparing to conventional FBMC and CP-OFDM, and in highly frequency-selective channels it has better BER performance than FBMC.…”

“…The difference in these methods is the location of offset-QAM (OQAM) modulated symbols in the time, frequency, and polarization domains. As described in [1], for DP-FBMC Structure I we separate the adjacent modulated and filtered OQAM symbols on two orthogonal polarizations by multiplexing symbols in time domain. By this approach we can remove the intrinsic interference that results from (temporally) adjacent symbols.…”

In a recent work we proposed a new radio access technique based on filter bank multi-carrier (FBMC) modulation using two orthogonal polarizations: dualpolarization 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.
