Abstract
This paper presents a step-by-step design and implementation of the transmitter section of a universal filtered multicarrier modulation (UFMC) system targeted for use in next-generation wireless communication systems. The development process includes four sequential stages: mathematical modeling and simulation of the UFMC system in MATLAB, system-level modeling in Simulink, hardware-oriented design using the Xilinx System Generator, and design verification using hardware co-simulation. The paper describes in detail the main functional blocks of the UFMC transmitter, including random data generation, QPSK modulation, serial-to-parallel conversions, zero padding, inverse discrete Fourier transform, digital upconversion, and subband filtering. Special attention is paid to the implementation of the system on a Xilinx Spartan-6 FPGA, taking into account the limitations of hardware resources and fixed-point representation accuracy. An elliptic filter and a Chebyshev filter of the second kind are studied for subband formation. Simulation results obtained in MATLAB and Simulink show that the use of an elliptic filter provides better spectral localization and more effective sidelobe suppression compared to a Chebyshev filter. These results confirm the practical applicability of the proposed UFMC architecture and its potential for further hardware implementation in 5G wireless communication systems.
