“…It was concluded that the performance degradation from synchronization errors is negligible provided that at least one subcarrier is left void between adjacent multiuser transmissions. The same conclusion has been drawn in [59]. In OFDMA, a single subcarrier does not suffice to separate the signals from different users.…”

“…In OFDMA, a single subcarrier does not suffice to separate the signals from different users. At the price of a complexity increase, the sensitivity to synchronization errors can be reduced by resorting to interference mitigation techniques [59], [60]. Section IV-C4 further delves into the robustness against synchronization errors, by carrying out a performance evaluation of FBMC/OQAM and OFDM when tight synchronization is not attained.…”

“…Multicarrier schemes based on filter banks (FBMC) have recently shown the potential of overcoming such drawbacks [8,9], thus providing an attractive alternative to OFDM, at the cost of some additional complexity http://asp.eurasipjournals.com/content/2014/1/66 and delay [10]. When combined with offset quadrature amplitude modulation (OQAM), prototype filters with good localization in both time and frequency are possible, resulting in the so-called FBMC/OQAM modulation scheme [11].…”

Preamble-based channel estimation in filter bank-based multicarrier (FBMC) systems using offset quadrature amplitude modulation (OQAM) has been extensively studied in the last few years, due to the many advantages this modulation scheme can offer over cyclic prefix (CP)-based orthogonal frequency division multiplexing (OFDM) and in view of the interesting challenges posed on the channel estimator by the interference effect inherent in such an FBMC system. In particular, preambles of short duration and of both the block (full) and comb (sparse) types were designed so as to minimize the channel estimation mean squared error (MSE) subject to a given transmit energy. In the light of the important role that relay-based cooperative networks are expected to play in future wireless communication systems, it is of interest to consider FBMC/OQAM, and in particular questions associated to preamble-based channel estimation, in such a context as well. The goal of this paper is to address these problems and come up with optimal solutions that extend existing results in a single relay-based cooperative network. Both low and medium frequency selective channels are considered. In addition to optimal preamble and estimator design, the equalization/detection task is studied, shedding light to a relay-generated interference effect and proposing a simple way to come over it. The reported simulation results corroborate the analysis and reveal interesting behavior with respect to channel frequency selectivity and signal-to-noise ratio.

“…In filter bank multicarrier (FBMC) systems such as IOTA, on the other hand, near-optimal performance is achieved without any additional signal processing, such as interference cancellation, due to the excellent frequency-localized filters employed in FBMCbased systems [12]. The added complexity arising from IC blocks in an OFDM-based system makes it significantly more complex than its IOTA counterpart.…”

Orthogonal Frequency Division Multiplexing (OFDM) technique has gained increasing popularity in both wired and wireless communication systems. However, in the conventional OFDM systems the insertion of a cyclic prefix (CP) and the transmission of periodic training sequences for purpose of channel estimation decrease the system's spectral efficiency. As an alternative to OFDM, isotropic orthogonal transform algorithm (IOTA) based multicarrier system adopts a proper pulse shaping with good time and frequency localization properties to avoid interference and maintain orthogonality in real field among sub-carriers without the use of CP. In this paper, we propose linearly precoded IOTA based multicarrier systems to achieve blind channel estimation by utilizing the structure of auto-correlation and cross-correlation matrices introduced by precoding. The results 1 show that the proposed IOTA based multicarrier systems achieve better power and spectral efficiency compared to the conventional OFDM systems.
