FBMC transmission system was proposed as an alternative approach to OFDM system since it has a higher spectral efficiency. One of the characteristics of FBMC is that the demodulated transmitted symbols are accompanied by interference terms caused by the neighboring transmitted data in time and frequency domain. The presence of this interference is an issue for the Maximum Likelihood (ML) implementation when we consider a Spatial Multiplexing MIMO system. In this paper, we will propose a new FBMC scheme and transmission strategy in order to avoid this interference term. This proposed scheme (called FFT-FBMC) transforms the FBMC system into an equivalent system as simple as OFDM. First, we will develop the FFTFBMC in the case of SISO configuration, and then, we extend its application to Spatial Multiplexing MIMO configuration with Maximum Likelihood detection.
