On Spatial Data Multiplexing over Coded Filter-Bank Multicarrier with ML Detection

Abstract : Multicarrier modulation and especially CP-OFDM is widely used nowadays in several radio communications. How- ever, Filter Bank Multicarrier (FBMC) is a potential alternative to CP-OFDM since it does not require cyclic prefix and thus it has a higher spectral efficiency. One of the characteristics of FBMC is that it induces intrinsic interference among the transmitted data. The presence of this interference complicates the application of the MLD (Maximum Likelihood Detection) in the MIMO Spatial Data Multiplexing configuration which is known to improve the capacity. In this paper, we are interested in the encoded data case and we propose two receiver schemes. Both schemes are based on interference estimation and cancellation. The first one uses MMSE equalization in order to get an estimation of the intrinsic interference. The second one improves the interference estimation by exploiting the decided symbols around the considered time-frequency position. The performance of both approaches are assessed by simulation, and we show that the second approach exhibits either the same performance or better than OFDM.
