Comparative analysis of OFDM and GFDM

In recent past there are multiple, multicarrier techniques as an alternate of OFDM like Filter Bank Multi-Carrier (FBMC), Universal Filtered Multi-Carrier (UFMC) and Generalized Frequency Division Multiplexing (GFDM) as upcoming 5th Generation cellular systems. Performance of GFDM and OFDM needs to be investigated, since GFDM is increasing the performance of cellular communication system, so it needs to analyses the waveforms of both the techniques. In this work, we have checked the main characteristics of proposed wave forms and the relevant features. We conducted comparative analysis between GFDM and OFDM Bit error rate (BER) vs. Signal to Noise Ratio (SNR). GFDM is flexible in nature and its orthogonality gives it an edge over OFDM and which make it most suitable for the 5G technology.
