Abstract-In this paper, a combined non-orthogonal multiple access (NOMA) and multiband carrierless amplitude phase modulation (multiCAP) scheme is proposed for capacity enhancement of and flexible resource provisioning in 5G mobile networks. The proposed scheme is experimentally evaluated over a W-band millimeter wave radio-over fiber system. The evaluated NOMA-CAP system consists of six 1.25 GHz multiCAP bands and two NOMA levels with quadrature phase shift keying and can provide an aggregated transmission rate of 30 Gbit/s. The proposed system can dynamically adapt to different user densities and data rate requirements. Bit error rate performance is evaluated in two scenarios: a low user density scenario where the system capacity is evenly split between two users and a high user density scenario where NOMA and multiCAP are combined to serve up to twelve users with an assigned data rate of 2.5 Gbit/s each. The proposed system demonstrates how NOMA-CAP allows flexible resource provisioning and can adapt data rates depending on user density and requirements.Index Terms-Non-orthogonal multiple access, multi-band carrierless amplitude phase modulation, radio-over-fiber, millimeterwave communications, W-band wireless.

“…Ultra-wideband (uwb) wireless communication systems have been proposed as a low-cost and low-complexity solution for wireless access and personal area networks, offering high data rates and easy deployability as an unlicensed technology. [1][2][3] They received a lot of interest from industry and academia in the last decade, [3][4][5][6][7][8][9][10][11][12] and innovations in the industrial and commercial contexts as well as consumer areas still extend the possible areas of application. Most prominently, these are direct connections between devices, such as portable devices in personal area networks and device-to-device communications in connection with the internet of things, but also specific applications in areas sensitive to radio frequency interference, such as aircraft cabins and medical applications.…”

“…In this paper, 4 pulse shapes, proposed by the authors in previous studies 25,26 for high data-rate transmission under the SCRF mask, are discussed in more detail and their transmission performance is analyzed both analytically and through experimental demonstration. The suggested pulses are weighted linear combinations based on Gaussian, root-raised cosine, and hyperbolic secant squared type pulses as well as the frequency B-spline wavelet function.…”

SummaryThis paper addresses impulse-radio ultra-wideband (IR-UWB) transmission under the Russian spectral emission mask for unlicensed UWB radio communications. Four pulse shapes are proposed and their bit error rate (BER) performance is both estimated analytically and evaluated experimentally. Well-known shapes such as the Gaussian, root-raised cosine, hyperbolic secant, and the frequency B-spline wavelet are used to form linear combinations of component pulses, shaped to make efficient use of the spectral emission mask. Analytical BER values are derived using a Nakagami-m model, and good agreement is found with the experimentally obtained BER. The proposed pulse shapes allow IR-UWB transmission with BERs below the limit for a 7% overhead forward error correction, achieving distances of up to 6.5 m at 1 Gbit/s, 4.5 m at 1.25 Gbit/s, and 1 m at 1.66 Gbit/s. These results confirm the viability of IR-UWB transmission under the strict regulations of the Russian spectral emission mask.

SummaryExhaustive research is being done to establish the technologies and standards of the fifth generation (5G) of wireless communication systems. Some of the most challenging requirements of 5G systems are to increase the spectral efficiency and the capacity by a factor of 10 and 1,000, respectively. New technologies must offer an adequate framework for the 5G uses cases, which will enable higher capacities and the flexibility to adapt to dynamic scenarios. To cope with these challenging demands, a compelling approach is to exploit the current radio service bands by means of spectrum sharing and cooperation techniques, which alleviate the bandwidth requirements. In addition, advanced modulation schemes have a fundamental role in ensuring the best usage of the spectrum available in band‐limited systems. In this manuscript, we present the ultra‐wideband (UWB) technology as a prospective solution for 5G picocells and femtocells. Its main feature is its capability to operate simultaneously, without introducing interference, with current radio services on an unlicensed basis. We report experimental results reaching data rates up to 35 Gbit/s using the multiband approach of carrierless amplitude phase (MB‐CAP) modulation. To validate the versatility of the proposed system, our experimental tests were performed under the UWB regulations defined by the United States' Federal Communications Commission (FCC), the European Electronic Communications Committee (ECC), and the Russian State Committee for Radio Frequencies (SCRF). The regulations chosen provide diversity enough to demonstrate the capacity of MB‐CAP modulation to comply with worldwide regulations.
