GFDM SCHEME FOR A HIGH MOBILITY SCENARIO ON 5G NETWORK

As a candidate waveform for next-generation wireless communications, generalized frequency division multiplexing (GFDM) features several decent properties which make it promising. This, design is based on Generalized Frequency Division Multiplexing (GFDM) system and highlights the merits of modulation method for emerging fifth generation (5G) Wireless Communication Systems. Orthogonal Frequency Division Multiplexing (OFDM) is an excellent choice for fourth generation (4G). The channel estimation techniques for FBMC systems based on pilot arrangement is designed using Matlab. The channel estimation based on comb type pilot arrangement is applied through, different algorithms for both estimating channel at pilot frequencies and interpolating the channel. The estimation of channel at pilot frequencies is based on comb-type channel estimation with LMS estimate while the channel interpolation is done using linear interpolation, second order interpolation, low-pass interpolation, and spline cubic interpolation. The performances are measured on bit error rate with QAM as modulation schemes, and multi-path Rayleigh fading, and Auto-Regressive (AR) based fading channels as channel models.
