Abstract: The modulation scheme with Orthogonal frequency division multiplexing (OFDM) employs single cyclic prefix (CP) for each symbols whereas Generalized frequency division multiplexing (GFDM) utilizes single CP per symbol group; due to this reason OFDM is not bandwidth efficient. In this paper, the implementation of transmitter and receiver with minimum complexity for GFDM application is proposed. By incorporating Fourier transformation and inverse transformation techniques along with circular convolution in transceiver, the computation complexity is minimized. The effective band width of GFDM is improved by using cyclic prefix (CP) for each symbol. The simple receiver with matched filtration (MF), zero-force (ZF), and minimal mean-square-error (MMSE) scheme is proposed for demodulation. The results of the adopted scheme are compared with OFDM scheme.
