  • Practical aspects of increasing the spectral efficiency of PSK-n-signals due to intersymbol symbol interference

    The paper considers some practical aspects arising from the use of “transparency windows” (range of symbol time durations of information sequence when error probability per symbol due to intersymbol distortion is zero) to increase spectral efficiency in radio communication systems using multiposition phase-shift keyed signals with n discrete states. The functioning of communication systems was analyzed in the presence of frequency detuning and error produced by phase meter for various amplitude-frequency responses of a linear radio path. The admissible operating conditions and gains in information transfer rate of such systems are determined.

  • Fading Averaged-Spectral Efficiency Analysis of Average Interference-Constrained, Cooperative Device-to-Device Communication System

    We consider a two hop cooperative device-to-device (D2D) communication system. In it, a non-regenerative relay is subject to a tight constraint on the average interference it to the base station (BS). We derive interference- aware, spectral efficiency optimal relay amplification policy as a function of its local fading gains. We then derive expressions for fading-averaged spectral efficiency and its upper bound, and, present numerical results wherein we compare optimum amplification policy with fixed-amplification policy, and, also with a non-cooperative link. In all performance plots, we show that the optimal policy delivers superior performance when compared to fixed-amplification policy, and, non-cooperative link.

  • Designing transparent flexible-grid optical networks for maximum spectral efficiency [Invited]

    Higher-order modulation formats and spectral super-channels are key to maximizing spectral efficiency (SE) in next-generation optical transport networks, thereby postponing/minimizing expensive additional fiber rollouts and reconfigurable optical add/drop multiplexer node upgrades. A flexible dense wavelength division multiplexed (DWDM) grid is key to efficiently accommodating media channels requiring more (or less) than 50 GHz of contiguous spectrum. In particular, routing media channels consisting of multiple adjacent carriers enables packing them closer together and sharing a single pair of guard bands of adaptive width to cope with optical filtering. This effect is maximized by giving preference to deploying media channels with more carriers. However, designing the DWDM network in such a way can translate into resource overprovisioning whenever the traffic requirements between two nodes are below the (large) capacity of the most spectrally efficient media channel format that can be deployed between those nodes. This paper provides insight on how the set of media channels and the network design framework used impact the trade-off between maximizing SE and minimizing resource overprovisioning in transparent flexible-grid optical networks. Furthermore, it discusses enabling strategies to mitigate the risk of resource overprovisioning when maximizing network SE is the key design objective.

  • Spectral efficiency evaluation for non-orthogonal multiple access in Rayleigh fading

    This paper presents original analysis on the downlink spectral efficiency of non-orthogonal multiple access (NOMA) in Rayleigh fading environment. According to our accurate evaluation technique, a closed-form expression of NOMA spectral efficiency is proposed. With the closed form, the exact average of NOMA spectral efficiency can be achieved at different system parameters. Moreover, this closed form can be used to evaluate other orthogonal multiple access (OMA) techniques such as orthogonal frequency division multiple access (OFDMA).

  • Uplink spectral efficiency for non-orthogonal multiple access in Rayleigh fading

    This paper introduces original analysis on the uplink spectral efficiency of non-orthogonal multiple access (NOMA) in Rayleigh fading environment. According to the accurate Gaussian-based evaluation, a closed-form expression of the spectral efficiency is proposed. Also, this work is extended to the practical case in which the number of active users is random. Validated by the simulation, the presented closed form benefits us to calculate the exact average of uplink NOMA spectral efficiency at different system parameters, such as signal-to-noise ratio, active probability, number of employed subcarriers.
