Peak to Average Power Ratio and Bit Error Rate Analysis of MultiCarrier Modulation Techniques

Filter bank multicarrier (FBMC) modulation technique has potential output in the 5G systems.The choice of FBMC over Orthogonal Frequency Division Multiplexing (OFDM) is attributed to lower Peak to Average Power Ratio(PAPR) and reduced Bit Error Rate(BER). FBMC benefits due to its structural simplicity achieved in FIR filter realization. The PolyPhase Networking(PPN) filter banks are used in the implementation of FIR filters in FBMC. This in turn decomposes the wideband signals into a narrowband signal, resulting in lower PAPR of the whole system. Parameters like Signal to Noise Ratio(SNR),BER,PAPR are used as performance metrics to analyze OFDM, SC-FDMA and FBMC. Performance Metrics are compared across various channels like Rayleigh, Rician and Double Selective and their influence on the modulation techniques is discussed.
