    M-ary position and three-valued VMAP modem by Yi JIN, Le-nan WU, Jing YU, Lei DENG

    Published 2013-08-01
    “…In order to improve the spectral efficiency and energy efficiency of asymmetry,random-polar and very minimum amplitude and phase (ARP-VMAP) modulated signal simultaneously,an M-ary position and three-valued VMAP modulation was presented,and the receiver based on BP neural network or support vector machine demodulator was also designed.The contrast and analysis of the power spectrum,the −60 dB bandwidth,the spectral efficiency,and the demodulation performance among modulations as the ARP-VMAP,the three-valued VMAP,the M-ary position ARP-VMAP,and the M-ary position and three-valued VMAP,were carried out.Simulation results show that the new modem not only raise spectral efficiency,but also improve demodulation performance significantly.…”

    Scheme of extending elliptic curve method to three phases by Guiwen LUO

    Published 2018-12-01
    “…Elliptic curve method for integer factorization (ECM) is one of the most popular integer factorization algorithms,and it was firstly proposed by Lenstra in 1985.The original ECM contained just first phase.Since its invention,researches about the algorithm and implementation emerged up,among which the most important improvement is the extension to two phases proposed by Brent and Montgomery.This improvement tremendously strengthened ECM's capacity and efficiency.Elliptic curve method was extended to three phases.Extension method is kind of like “mixing together” the first phase and second phase.Compared to the best current two phases ECM,the new algorithm shows 2 advantages.First,under the same factorization parameters,the proposed algorithm improves the probability of finding out prime factor at the expense of negligible increasement of time.Second,when searching the same prime factor,the proposed algorithm can utilize smaller “smoothness parameters”.…”
