Performance analysis of OQAM based GFDM 5G systems under line of sight fading scenarios

As the world is moving towards everywhere and everything connected society, the fifth generation cellular systems is the leading technology to realize this dream. Generalized frequency division multiplexing (GFDM) is one of the physical layer waveform considered for 5G to overcome the deficiencies of the existing OFDM based 4G cellular systems such as Inter Carrier Interference (ICI) and Inter Symbol Interference (ISI). Already GFDM research proved that GFDM using Quadrature Amplitude Modulation (QAM) is more flexible and robust compared to the OFDM based LTE systems. In this paper, it is considered the performance of the Offset QAM based GFDM and the analysis of Symbol Error performance under various fading conditions. The performance of GFDM-OQAM system is evaluated for Outdoor fading profiles such as Highway Line of Sight (HLOS), Urban Approaching Line Of Sight (UALOS), and Rural Line of Sight (RLOS).
