“…The latter will be considered in our work due to their good compliance with FCC standard and ease of generation using analog circuits [22,26,30,32,[34][35][36]. Among the Gaussian family, the 5 th derivative pulse is the most conventional waveform which has been widely used in literature [32,[37][38][39][40][41][42].…”

Pulse design is critical for impulse radio communications, as it determines the transmission efficiency with respect to regulation spectral limits. In this paper, we propose the design of several novel pulse shapes relying on combinations of Gaussian derivatives with the target of improving the spectral efficiency. A general model for maximizing the efficiency of dual and triplet couplings is presented, employing the interior point global optimization algorithm. Then, the spectrum peak frequency is derived in closed form for any combination of two Gaussians with consecutive orders of derivation. The parameters controlling the time properties of the generated waveforms have been adequately adjusted to reach the best compliance with the spectral mask. Novel pulses have been investigated providing a high efficiency using simple generation mechanisms, which can be practically implemented via analog circuits. Results demonstrated the advantage of the proposed pulse shapes in terms of the bit error rate performance for 2 Gbps OOK and 1 Gbps PPM in AWGN and multipath channels.

“…In recent years, improvements at physical (PHY) and medium access control (MAC) layers of ISM and alternative wireless technologies have been proposed to mitigate the problems caused by the saturation of ISM frequency bands, [14][15][16][17][18][19][20]. One of these proposals is Impulse-Radio Ultra-Wideband (IR-UWB), which enables the deployment of robust short-range wireless networks with high node density, low complexity, high tolerance against interference and low power consumption, [14,[21][22][23][24][25].…”

“…Wireless transmission of IR-UWB signals is regulated by maximum transmit power limits defined by regulatory agencies in the form of spectral masks, [23][24][25]. The spectral masks aim is to enable harmonious coexistence between UWB systems and previously deployed wireless communication systems.…”

Design of Optical-Wireless IR-UWBoF Systems with Spectral Line Suppression Capabilities

et al. 2022

Impulse-Radio Ultra-Wide Band (IR-UWB) over Fiber (IR-UWBoF) has been proposed to interconnect IR-UWB-based deployments separated by hundreds of meters or even kilometers. IR-UWB transmissions must comply with spectral masks provided by radio spectrum regulatory agencies. The maximum transmit power of an IR-UWB signal is adversely affected by the presence of spectral lines in its Power Spectral Density (PSD). Thus, it is desirable that the PSD of signals generated by IR-UWBoF systems does not show spectral lines. Previous works have shown the feasibility of deploying of optical-wireless IR-UWBoF systems. However, most of these proposals report PSDs showing spectral lines. To the best of our knowledge, spectral line suppression has not been previously studied for optical-wireless IR-UWBoF systems. This work shows the design and implementation of optical-wireless IR-UWBoF systems generating signals with Spectral Line-Free (SLF) PSDs. The proposal considers the use the use of a specifically designed convolutional code combined with Binary Phase Shift Keying (BPSK) or Quaternary Biorthogonal Pulse Position Modulation (Q-BOPPM) to provide a SLF PSD in IR-UWBoF systems. A testbed consisting of 30 km of single-mode optical fiber (SMF) concatenated to a 20 cm wireless link was physically implemented. The results show that a SLF PSD is achieved for both the optical and the wireless transmissions, even when the binary data source feeding the system is not perfectly random.
