    Approximately optimum power allocation based on ergodic capacity for cooperative communication systems by LIN Fei1, LUO Tao1, LU An-qiong1, YUE Guang-xin1

    Published 2009-01-01
    “…Conventional half-duplex amplify-and-forward(AF) method always adopted cooperative communications model regardless the fading state of the channel,which made insufficient use of the degrees of freedom of the system in a way.So,the problem about "when to cooperate" and the optimum allocation of transmitted power were discussed.An exact ergodic capacity formulation and corresponding upper bound were first derived for a two-user AF cooperative communications system.And then an approximately optimum power allocation scheme(AOPA) was proposed by making use of the upper bound as cost function.Whether the AOPA scheme adopting the cooperative model or not based on the comparison about the channel gains of source-to-destination with that of relay-to-destination.Finally,the system per-formances were analyzed with AOPA scheme when the relay moved in terms of the random direction model.Theoretical analysis and simulation results show that the AOPA outperforms the EPA scheme both in ergodic capacity and symbol-error-rate(SER) performance.…”

    Blind data recovery of single-channel mixed signals based on Turbo equalization and channel estimation by Dong-ling ZHANG, Yong YANG, Jing LI, Lin-dong GE

    Published 2014-01-01
    “…The timing synchronization is the key technique of the single-channel blind signal receiver.The single-channel blind recovery algorithm based on Turbo equalization was proposed,which does not require the timing synchronization.In the algorithm,the timing offset is taken as inter-symbol interference channel,which can improve the restorability of source signals by the feedback soft information between channel estimation and the turbo equalization.The primary works include the research on initial blind equalization algorithm,the channel estimation algorithm,MMSE equalization algorithm for the mixed signals and the soft information interaction among those three algorithms.The proposed algorithm has low computational complexity and small computational load,which can be applied to high-order modulated signals.Simulation results show that,good performance could be achieved for BPSK,QPSK and 8PSK modulated signals.In addition,the proposed algorithm is suitable for both equal power and unequal power signals.…”

    Object-based change detection method for high-resolution remote sensing image combining shadow compensation and multi-scale fusion by Chao WANG, Xuehong ZHANG, Aiye SHI, Dan LI, Yi SHEN

    Published 2018-09-01
    “…As an interpreting symbol of remote sensing images,shadow,however,brings about “pseudo changes”,which is one of the main sources leading to error detection in high-resolution remote sensing image change detection.For this issue,an object-based high-resolution remote sensing image change detection method was proposed combining with shadow compensation and multi-scale fusion.In the object orientation detection framework,the shadows in the remote sensing images were extracted.Then multi-scale change detection was conducted with shadow compensation.In the process,an objective function was constructed of mutual scale information minimization to realize the adaptive extraction of scale parameters.Based on this,combined with the shadow compensation factor,a multi-scale decision-level fusion strategy built on D-S theory of evidence was designed,and the levels of change intensity were further divided.The experiments show that the method is effective in solving the error detection problem caused by shadow,significantly improving the precision of change detection.…”
