The Powerful Activity for FBMC-OQAM Wireless Communication System Relies on Slantlet Transform

Abstract

There are many candidate waveforms for the next-era communication system. Filter bank multi-carrier (FBMC) This system depends on offset quadrature amplitude modulation (OQAM) is one of them. Compared to OFDM, it can offer faster data rates and improved spectrum efficiency. The OFDM has a few disadvantages which as a high PAPR resulting in the requirement for high-power amplifiers. So, to overcome this problem, the FBMC system with OQAM is used. In this manuscript, a proposed method was designed using the modified technique through the slantlet transform (ST) to raise the activity for the system. This scheme is suitable for providing lower losses, higher data rates, and for better spectral efficiency. a proposed method that uses the ST gives a modified performance than the fast fourier transform (FFT). Many parameters were applied to test the activity of the system such As Power spectral density, prototype filters, signal power, velocity, carrier frequency, modulation order, power delay profile, channel doppler model, overlap factor, and efficiency. In all these parameters it can be noticed that the proposed system based on ST has overcome the other systems and gives higher performance.
