Doctoral Dissertation Examines FBMC Modulation for 5G Using SDR

The Department of Electrical Engineering at the University of Technology awarded a Ph.D. to Mohammed Qasim Mohammed for his dissertation titled “Filter Bank Multicarrier Modulation for 5G Mobile Communication Based on SDR.”

The study delves into Filter Bank Multicarrier (FBMC) modulation, a promising technology for fifth-generation (5G) mobile communications, focusing on aspects such as implementation complexity, channel estimation, synchronization, and applications in Cognitive Radio (CR).

The research evaluated the performance of FBMC in multi-path and time-varying communication channels using LTE and 5G NR parameters. Findings revealed:

• A 4-15 dB improvement in Bit Error Rate (BER) performance of FBMC over CP-OFDM, depending on 5G parameters.
• A 76% increase in spectral efficiency compared to CP-OFDM in LTE and 29% in 5G scenarios.

The dissertation highlights the advantages of FBMC in modern wireless communication systems, particularly in improving efficiency and reducing errors.
