| Summary: | Due to its flexible nature, Generalized Frequency Division Multiplexing (GFDM) has recently
received a great deal of attention making such waveform a suitable candidate for future 5G networks. The concept and implementation for the prototype using hardware platforms are now made available. GFDM removes the detrimental effects of multipath fading channel into flat narrow band channels since the Bit Error Rate (BER) is the target to be satisfied with any kind of wireless communication systems. In this paper, the new suggested idea is to take advantage of concatenating two kinds of codes for channel coding which are Turbo Code (TC) and Low Density Parity Check Code (LDPC) through multipath fading channels. The TC and LDPC are implemented in series respectively at the transmitter with their inverse order at the receiver. This idea is applied to the fifth Generation (5G) of mobile network for different kind of fading channels. As a result, the BER is considerably reduced through using the TC and LDPC codes which strengthen the obtained simulation results. The Computational complexity of different GFDM system implementations are also analyzed in detail and compared, in the lights of which substantial conclusions are drawn.
