“…We then analyzed the power spectral density (PSD) for the binary case, leading us to demonstrate that the PSD of the SSB-FSK signal is unilateral with respect to the carrier frequency (f c ), and almost all of the power is concentrated in the first period of the frequency band. Finally, in [3], we presented an analytical expression for the power spectral density (PSD) for binary and quaternary SSB-FSK.…”

This study reports on a single side band spectrum directly generated by a continuous phase modulation (CPM) signal. This signal is analyzed in terms of modulation indices, pulse lengths, and pulse widths, all of which affect error probabilities, bandwidths, and SSB property. The error probability performance is based on an approximation of the minimum Euclidean distance. A numerical power spectral density calculation for this particular SSB modulation in terms of modulation index is presented. Reasonable tradeoffs in designing modulation schemes have been defined using multi-objective optimization to ensure sizable improvements in bit error rate (BER) and spectral efficiencies, without losing the property of being a SSB signal. Performance comparisons are made with known CPM schemes, e.g., Gaussian Minimum Shift Keying (GMSK) and Raised Cosine based CPM (RC).

“…Frequency modulation of a constant envelope complex signal is investigated, where the information is carried in the phase rather than in the amplitude. A new constant envelope FSK-CPM waveform was recently proposed in [20]. Its frequency pulse has the property to directly generate a narrow single side band (SSB) spectrum.…”

Abstract-The radio spectrum above 90GHz offers opportunities for huge signal bandwidths, and thus unprecedented increase in the wireless network capacity, beyond the performance defined for the 5G technology. This spectrum is essentially exploited for scientific services, but attracts nowadays many interest within the wireless telecommunications research community, following the same trend as in previous network generations. The BRAVE project that was launched at early 2018, aims at the elaboration of new waveforms able to efficiently operate in the 90-200 GHz spectrum. The researches rely on three complementary works: the definition of relevant communications scenarios (spectrum usage, application, environment, etc); the development of realistic models for the physical layer (propagation channel and RF equipments); and the elaboration of a single-carrier modulation compliant with the propagation channel properties, and allowing improvement on the spectral and energy efficiency. The motivation for this work, and the preliminary results on the waveform definition, are exposed in the present paper.Index Terms-Tbit/s, beyond-5G, above-90GHz, single-carrier.I. INTRODUCTION The activities of research and industrialization concerning the fifth generation (5G) of wireless communication systems are well-under way. Several solutions are proposed for standardization starting with 5G-NR (New Radio) [1]. There are three main objectives driving the development of 5G: the support to extreme wireless broadband services for applications such as the virtual and augmented realities, the 3D 4K video, cloud services, etc.; the connectivity for massive Internet of Thing (IoT) applications as: smart cities and factories, wireless health care; and the support of mission-critical services such as for autonomous vehicle, or security, with strong requirements on latency, guaranteed throughput, etc.All these target applications have highly different needs, but make 5G required to offer: throughputs in the order of Gbps with sub-millisecond latency along with 1000x capacity increase, and 100x connected devices per cell compared to nowadays existing mobile networks. Dense small-cell deployments, centralized RAN (Radio Access Network), advanced MIMO schemes and new millimeter-Wave (mmW) bands are key enablers to achieve the expected increase in spectral efficiency and capacity [2]. Frequency bands 26 or 28 GHz and 39 or 42 GHz will be likely selected for early 5G deployments.Alongside these 5G initiatives, the scientific community has also launched many investigations on the beyond 5G

“…The problem of calculating P (ε) is similar to the calculation of the power spectrum density in digital communication for binary phase pulse modulation, see [43,44]. In this analogy, the electronic quantum phase corresponds to the modulated phase,the voltage pulses to frequency pulses, the energy to frequency and P (ε) to electromagnetic power.…”

The recent realization of single electron sources lets envision performing electron quantum optics experiments, where electrons can be viewed as flying qubits propagating in a ballistic conductor. To date, all electron sources operate in a periodic electron injection mode leading to energy spectrum singularities in various physical observables which sometime hide the bare nature of physical effects. To go beyond, we propose a spread-spectrum approach where electron flying qubits are injected in a non-periodic manner following a pseudo-random binary bit pattern. Extending the Floquet scattering theory approach from periodic to spread-spectrum drive, the shot noise of pseudo-random binary sequences of single electron injection can be calculated for leviton and non-leviton sources. Our new approach allows to disentangle the physics of the manipulated excitations from that of the injection protocol. In particular, the spread spectrum approach is shown to provide a better knowledge of electronic Hong Ou Mandel correlations and to clarify the nature of the pulse train coherence and the role of the dynamical orthogonality catastrophe for non-integer charge injection.
