The high demand for rail transportation services has encouraged the development of research in the field of railways. In the operation of trains, telecommunications has a vital function because it is related to passenger safety. The high speed of train operation requires a telecommunication system that has a high transmission capability of up to Gbps units. Meanwhile, GSM-R technology still has a peak data rate of 172 Kbps while LTE-R still has a peak data rate of 20 Mbps. Therefore, in this study, the use of alternative waveforms in the railway environment is discussed. This study discusses the analysis of the precoded MIMO-GFDM system based on BER parameters. GFDM (Generalized Frequency Division Multiplexing) is one of the waveforms that has been proposed as a candidate for 5G communication. Meanwhile, the use of MIMO in GFDM systems aims to maintain system performance in dealing with multipath channels. The results obtained are that the Precoded MIMO-GFDM system has the same bit error rate when compared to MIMO-OFDM and the Precoded MIMO-GFDM system has optimal results when using 16 subcarriers and 32 subsymbols.
