Robust Interference Mitigation on Modified Filterbank Multicarrier Spread-Spectrum Waveforms

As the demand for spectrum increases, significant research has been devoted to the development of interference-resistant waveforms. In this paper, we propose modified filterbank multicarrier spread spectrum (MFBMC-SS), a modification to the existing filterbank multicarrier spread spectrum (FBMC-SS) scheme that increases spectral and temporal diversity to be able to resolve and remove interference while operating at a low signal-to-noise ratio (SNR). Optimal interference rejection techniques for MFBMC-SS are derived. Robust order statistics and Gaussian mixture models are considered and simulated for interference parameter detection to apply to the derived rejection techniques. These simulations give a characterization for MFBMC-SS under different interference environments and with different interference rejection techniques.
