    Unifying error-correcting code/Narain CFT correspondences via lattices over integers of cyclotomic fields by Shun'ya Mizoguchi, Takumi Oikawa

    Published 2025-03-01
    “…This code-lattice construction is redescribed in terms of root and weight lattices of Lie algebras, which allows to construct lattices for codes over rings Zq with non-prime q. Corresponding Narain CFTs are found for codes embedded into quotient rings of root and weight lattices of ADE series, except E8 and Dk with k even. …”

    Capacity analysis for MISO-UWOC systems over GGD weak turbulence with zero boresight pointing error by Yueheng LI, Yining XU, Meiyan JU, Ping HUANG

    Published 2023-08-01
    “…Generalized Gamma distribution (GGD) was chosen to describe the weak oceanic turbulence, and a new hybrid fading channel model that integrated the GGD weak turbulence, the zero boresight pointing error, and the implicit path loss plus multipath propagation characterized by the fading free impulse response (FFIR) was proposed.Subsequently, mathematical expressions for the ergodic capacity and outage capacity of the multiple-input single-output underwater wireless optical communication (MISO-UWOC) systems were derived through the Meijer-G function under a selective transmission (ST) diversity scheme especially while inter-symbol interference (ISI) effects were considered or not.Finally, the correctness of the theoretical formulas derived above was verified by some numerical results.The simulation results show that with the introduction of the ST diversity, the ergodic capacity of the MISO-UWOC systems, taking the transmission ports N=2 as an example, is at least 1.3 times better than that of the conventional point-to-point (P2P) transmission under the same channel condition and system parameters, while the maximum outage capacity decreases is also more than 60% compared with the conventional P2P one.However, the introduction of the ISI will severely reduce this performance improvement.…”

    Moisture-based green energy harvesting over 600 hours via photocatalysis-enhanced hydrovoltaic effect by Peng Duan, Chenxing Wang, Yinpeng Huang, Chunqiao Fu, Xulei Lu, Yong Zhang, Yuming Yao, Lei Chen, Qi-Chang He, Linmao Qian, Tingting Yang

    Published 2025-01-01
    “…Here, we propose a design for reconstructing the ion concentration gradient by coupling photocatalytic hydrogen evolution reaction with hydrovoltaic effect, to report a moisture-enabled electric generator (MEG) with continuous current output. We show that the introduction of the photocatalytic layer not only absorbs light energy to greatly increase the power generation of the MEG (500% power density enhancement), but more importantly, the photocatalytic hydrogen evolution process consumes the pre-stacked ions to restore the ion concentration gradient, allowing the MEG to continuously output current for more than 600 hours, which is 1 to 2 orders of magnitude higher than the great majority of existed MEGs in terms of the current output duration.…”

    Nondata-aided error vector magnitude based adaptive modulation over rapidly time-varying channels by Fan YANG, Xiao-ping ZENG, Xin JIAN, Ji-hua ZHOU, Ding-liang RUAN, Yi-wen GAO

    Published 2017-03-01
    “…A novel nondata-aided error vector magnitude based adaptive modulation(NDA-EVM-AM) was proposed to solve the problem of lower spectral efficiency over rapidly time-varying wireless channels.Namely,NDA-EVM was considered as a metric to reflect the rapid change of time-varying channels.The unified model to calculate different modulation order of NDA-EVM was analytically derived,with which the relationship between NDA-EVM and bit error rate (BER) for each modulation order was presented.Thereafter,the mechanism to adaptively select the modulation orders of multilevel quadrature amplitude modulation (MQAM) signals was designed to guarantee the predefined BER.Taking the two rapidly time-varying channels proposed for high-speed railway scenarios as examples,numerical results are conducted to verify the effectiveness of the proposed algorithm.It shows that NDA-EVM estimation has the lest root mean square error than data-aided error vector magnitude (DA-EVM) estimation and signal to noise ratio estimation.The proposed algorithm has better accuracy in aspects of channel quality estimation and modulation orders adjustment,Compared with conventional data-aided error vector magnitude based-adaptive modulation (DA-EVM-AM),the accuracy improves by 7.9%,spectral efficiency improves by 0.53 bit·s<sup>−1</sup>·Hz<sup>−1</sup>,and compared with signal to noise ratio based-adaptive modulation (SNR-AM),the accuracy improves by 15.7%,spectral efficiency improves by 0.82 bit·s<sup>−1</sup>·Hz<sup>−1</sup>.…”
