Decoding Schemes for FBMC with Single-Delay STTC
Orthogonally multiplexed Quadrature Amplitude Modulation (O-QAM) with Filter Banks based Multi Carrier modulation (FBMC) is a multi-carrier modulation scheme that can be considered as an alternative to the conventional orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP) for transmission over multi-path fading channels. However, as OQAM-based FBMC is based on real orthogonality, transmission over a complex-valued channel makes the decoding process more challenging compared to CP-OFDM case. Moreover, if we apply Multiple Input Multiple Output (MIMO) techniques to OQAM-based FBMC, the decoding schemes are different from the ones used in CP-OFDM. In this paper, we consider the combination of OQAM-based FBMC with single delay Space-Time Trellis Coding (STTC). We extend the decoding process presented earlier in the case of Nt = 2 transmit antennas to greater values of Nt. Then, for Nt 2, we make an analysis of the theoretical and simulation performance of ML and Viter...
