Doubly-Selective Channel Estimation in Fbmc-Oqam and Ofdm Systems

Pathan Emaran Samadkhan, M. Lavanya


The Spectrum efficiency for 5G networks can be achieved by Filter Bank Multi Carrier / Orthogonal Quadrature Amplitude Modulation (FBMC / OQAM) that avoids the usage of guard band. FBMC is very sensitive to Carrier Frequency Offset (CFO) and Timing Offset (TO). This paper proposes Zadoff-chu sequence based preamble or pilot is used to design the FBMC frame for synchronize more with receiver to achieve sufficient channel estimation and phase tracking which reduces the carrier frequency and timing synchronization. This method helps to control the out of band emissions and create non-orthogonal waveforms to investigate the overall system performance such as Bit Error Rate (BER) over AWGN channels. The performance metrics such as Complementary Cumulative Distribution Curve (CCDF) for FBMC signal with different multicarrier to analyze the Peak to Average Power Ratio (PAPR) is obtained by simulation. The simulation result proves that FBMC outperforms well when compared with other multicarrier systems.
