    Upper Bound on the Bit Error Probability of Systematic Binary Linear Codes via Their Weight Spectra by Jia Liu, Mingyu Zhang, Chaoyong Wang, Rongjun Chen, Xiaofeng An, Yufei Wang

    Published 2020-01-01
    “…The proposed bound on the bit error probability is derived with the framework of Gallager’s first bounding technique (GFBT), where the Gallager region is defined to be an irregular high-dimensional geometry by using a list decoding algorithm. The proposed bound on the bit error probability requires only the knowledge of weight spectra, which is helpful when the input-output weight enumerating function (IOWEF) is not available. …”

    Hybrid Filtered-x Adaptive Vibration Control with Internal Feedback and Online Identification by Lihua Yang, Shuyong Liu, Haipeng Zhang, Haiping Wu, Haifeng Li, Jian Jiang

    Published 2018-01-01
    “…In this paper, a novel hybrid improved adaptive control strategy, feedback and online identification filtered-x LMS, namely, FOFxlms, is proposed, which introduces the residual errors to correct variable step-size, uses the estimated primary path to improve online identification, and applies internal feedback to compensate for the feedforward control. Then the FOFxlms algorithm is applied to a double-layer vibration isolation system of submarine rotating equipment, and the simulation results show that the normalized variable step-size with residual error can effectively improve convergence speed, the internal feedback can efficaciously compensate for steady-state control accuracy, and the online identification can dynamically identify the time-varying characteristics of the secondary path. …”

    Time-varying channel estimation in OFDM systems based on multiple symbols BEM by Yong DING, Shan OUYANG, Yue-lei XIE, Jun-zheng JIANG, Xiao-mao CHEN

    Published 2017-03-01
    “…In view of the problem of low frequency spectrum utilization for the time-varying channel estimation in orthogonal frequency division multiplexing(OFDM) systems based on basis expansion model (BEM),a new method based on multiple symbols BEM was proposed.Compared with the conventional method based on single symbol,the proposed method reduced the subcarriers for pilots.And by means of the baseline tilting technique,the new method mitigated the Gibbs phenomenon caused by Fourier series expansion.The theoretical analysis reveals that the channel model error is reduced due to the introduction of the baseline tilting technique when the normalized Doppler frequency is no more than <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML"> <mfrac> <mrow> <mfrac> <mn>1</mn> <mn>2</mn> </mfrac> <mo>−</mo><mfrac> <mn>1</mn> <mi>M</mi> </mfrac> </mrow> <mrow> <mn>1</mn><mo>+</mo><mfrac> <mrow> <msub> <mi>N</mi> <mi>g</mi> </msub> </mrow> <mi>N</mi> </mfrac> </mrow> </mfrac> <mtext> </mtext></math></inline-formula>.Finally,the numerical simulation shows that compared with conventional methods,the proposed algorithm achieves significant improvement on the estimation error performance and bit error rate (BER) performance under the conditions of the corresponding time-varying channel.…”
