description: The subject of the graduate qualification work is âImproving data transmission efficiency in the 5G mobile communication system by applying FBMC signalâ. This thesis focuses on improving the efficiency of data transmission in the 5G mobile communication system by using FBMC/OQAM (Filter Bank Multicarrier with Offset Quadrature Amplitude Modulation) signal. The big disadvantages of OFDM (Orthogonal Frequency Division Multiplexing) technology are high OOBE (Out-of-band Emission) due to the use of a rectangular window for signal generation, low spectral efficiency due to the presence of a cyclic prefix to protect against Intersymbol Interference (ISI) and Intercarrier Interference (ICI). These disadvantages lead to a decrease in the efficiency of data transmission in the 5G mobile communication system. In this thesis, various approaches to the transmitting and receiving of FBMC/OQAM signals are investigated and a new approach to the generation of FBMC/OQAM signals to reduce the computational complexity of the implementation is proposed. Built bit error probability curves for the transmission of FBMC/OQAM and (CP-)OFDM signals through different channels, based on which a comparison of the effectiveness of 5G mobile communication system using FBMC/OQAM and (CP-)OFDM signals. In addition, this thesis also presents a comparison of the computational complexity of different approaches for implementing FBMC/OQAM signals and OFDM signals. Simulation results show that FBMC/OQAM (FS-FBMC/OQAM, PPN-FBMC/OQAM) signals have higher spectral efficiency than CP-OFDM signals and the spectral gain is ~7%. However, the computational complexity of the FS-FBMC/OQAM signal implementation is significantly higher than the OFDM signal (by ~11 times at an overlap factorÂ KÂ = 4). Reducing the computational complexity of the implementation of the signal FBMC/OQAM can be done by applying a polyphase filter structure, but the energy efficiency decreases by several dB, depending on the transmission channel.
