Augmentation of spectral efficiency using APSK in FBMC to assess high data rate

Abstract

There are various techniques which have been developed to improvise the modulation technique exploited in the system which were intended to enhance the data rate and bandwidth of the 5G network. Various researchers worked on OFDM modulation technique in order to enhance the efficiency as it is successfully working on 4G networks. Although utilization of OFDM in 5G networks will not provide the expected outcomes due to some flaws. This paper proposed a system that induced FBMC (Filter Bank Multi-Carrier) modulation technique which is capable of delivering higher spectral efficiency than OFDM. Proposed method employed APSK (Amplitude Phase Shift Modulation) for the modulation of sub carriers. The idea of implementing APSK in FBMC is to optimize the peak to average power ratio and also reduces bit error rate. The techniques proposed in the system, aimed to achieve high efficiency in terms of data rate and bandwidth with less power consumption. By using MATLAB all the simulations will be performed to analyze the results of spectral efficiency in terms of BER vs Eb/No (SNR) and power spectral density.
