    Forced Oscillation of Second-Order Half-Linear Dynamic Equations on Time Scales by Quanwen Lin, Baoguo Jia, Qiru Wang

    Published 2010-01-01
    “…We will establish a new interval oscillation criterion for second-order half-linear dynamic equation (r(t)[xΔ(t)]α)Δ+p(t)xα(σ(t))=f(t) on a time scale T which is unbounded, which is a extension of the oscillation result for second order linear dynamic equation established by Erbe et al. (2008). …”

    Joint time-frequency interference alignment in the frequency-selective Gaussian interference channel by JING Zhen-hai1, BAI Bao-ming1, MA Xiao3

    Published 2011-01-01
    “…To make up for the limitation that the traditional interference alignment can only align the signal in one dimensional domain,a novel joint time-frequency interference alignment scheme was put forward in the frequency-selective Gaussian interference channel(GIC).After the frequency-selective GIC was changed into a set of parallel GICs,a set of time-frequency alignment matrices were employed which aligned the interference signal not only in time domain but also in frequency domain.An algorithm for calculating the time-frequency alignment matrices was presented based on the convex optimization.Computer simulations show that the joint time-frequency interference alignment can obtain the same performance as the traditional interference alignment while the joint time-frequency interference alignment can shorten the decoding time or reduce the occupation of the frequency resource.The joint time-frequency interference alignment scheme is an extension of the traditional interference alignment and provides a more flexible resource allocation approach between time domain and frequency domain.…”
