Frequency spreading filter bank multicarrier (FS-FBMC) is widely considered as a potential candidate for the air interface of the next-generation mobile communication, 5G. The prototype filter plays a pivot role in the frequency–time confinements to obtain a better performance, as a result of mitigating the inter-carrier interference and the inter-symbol interference.

In this work, the architecture of single radio access for both FS-FBMC and orthogonal frequency division multiplexing OFDM is presented to demonstrate the idea of combining both multicarrier in a single hardware and reusing OFDM resources for FS-FBMC. The FS-FBMC transceiver is analyzed, and two recently designed Nyquist filters are adopted as prototype filters. The frequency-domain coefficients are calculated for the new Nyquist filters to be suitable for FS-FBMC prototype filters, and the interference coefficients on the adjacent time–frequency grids of the new filters and PHYDYAS are calculated using different overlapping factor. Also, a novel single symbol preamble channel estimation is proposed and a single tap equalizer in the frequency domain is used to track the channel state and recover the distorted data similar to the conventional OFDM. The error performance over noisy and mobile fading channels, and as a function of non-linear distortion demonstrates the strength of FS-FBMC based on the new well-localized prototype filters in the time–frequency domains, which addresses the main shortages of the OFDM that arise from poor spectral stopband characteristics and the amplitude fluctuation over the transmit symbols. Moreover, it is found that the new prototype filters outperform the most commonly used filter, PHYDYAS. Also, it is showed that the proposed channel estimation and new prototype filters support single radio access based OFDM and FS-FBMC that motivate industry to consider FS-FBMC as a promising air interface for 5G.
