Design and Hardware Implementation of Fractal Comb-Structured Signals

Currently, wireless communications networks are developing very quickly and are utilizing more spectral resources. Despite all the efforts to improve wireless network performance and energy-efficiency, spectrum is still overloaded. This problem results in decreasing signal strength and increasing influence of interference. Therefore, it is highly important to develop new methods of data transmission in wireless networks, providing better energy- and spectral-efficiency. In this paper, we propose new types of fractional comb-structured signals. We developed signal models for different types of fractional signals. We also developed hardware for fractional signal generation and transmission based on the PIC16F873 microcontroller. Finally, we conducted experimental analysis of the obtained signals via oscilloscope. Results show that the proposed signal model can be implemented in wideband wireless communications networks, providing good characteristics.
