WITHDRAWN: Reduction of FBMC/OQAM imaginary intrusion compared to OFDM

Abstract

In comparison to the OFDM (Orthogonal Frequency Division), Filter Bank multicarrying function (FBMC) has superior spectral properties, which complicates operational multiple input and mixed outputs. By extending a symbol in time, we can totally remove the imaginary interference. This gives the ease of applying all MIMO strategies known in OFDM to FBMC. The approach itself is of little complexity since it is based on hadamard matrices. While FBMC spreading allows complicated orthogonality to be restored in one block of communication, interference may be seen from the neighbouring blocks. By inserting a time security slot, the signal-to - interference ratio can also be improved. Furthermore, we examine the effect on the propagation process of a time channel. The estimation of the potential for Bit Error in double selective channels has been improved. In doubly selective channels, that is, time selectivity and frequency selectivity, we study the degeneration of output between OFDM and FBMC. In order to do this, we derive closed-form Bit Error Probability (BEP) terminology for the arbitrary linear modulation methods dependent on one-tap equalizers, in which our general BEP expressions include OFDM and FBMC.
