Generalized Frequency Division Multiplexing (GFDM) is a novel filtered multicarrier transmission scheme that provides the flexibility required by 5G applications. Its robustness against fading multipath environments can be increased by space-time coding (STC) at the transmitter when the receiver complexity should be kept minimal. In this paper we investigate the application of the Alamouti-STC in GFDM with a maximum ratio combining (MRC) receiver. We show the application to be straight-forward in contrast to the difficulties that arise in FBMC/OQAM due to its OQAM-modulation. The performance is evaluated by comparing coded GFDM and OFDM transmissions in frequency-selective fading channels.
