Abstract: As the world, is looking for more data speeds along with support for M2M communication in the next generation (5G), the current orthogonal frequency division multiplexing (OFDM) has limitations such as high PAPR, spectrum wastage due to cyclic prefix (CP), out of band (OOB) emissions. To overcome these limitations, 5G researchers is looking for different wave forms and filter bank multi carrier (FBMC) waveform is one of the prime contenders. In this paper, it has been implemented, the poly-phase network filter bank multi carrier (PPN-FBMC), which reduces the high complexity and computations. A prototype filter for the PPN FBMC with high overlapping factors (K = 6 and 8) are implemented. It also simulates FBMC system using Matlab Software, to characterise and analyse the 5G candidate waveform FBMC and compare with OFDM, in terms of error vector magnitude (EVM), peak to average power ratio (PAR), and power spectral density (PSD) performance. The simulated results prove that FBMC outperforms the OFDM systems in all the above mentioned aspects, even under noisy conditions.
