    Indoor positioning algorithm research based on the typicality judgment of RSS by Jia-ying WU, Wei-hong XU, Shun-ming CHEN, Ping LI

    Published 2014-11-01
    “…In the process of indoor location based on RSS fingerprint,the quality of the obtained similar point set is a key factor for a successful position.And the locating point’s RSS is an important reason which affects the quality of the similar point set.By analyzing the distribution of D-RSS,the concept of RSS’s typicality was proposed firstly,and an indoor localization algorithm based on typicality judgment of RSS was also presented.According to the principle that the RSS values and the effective similar sample points,a typicality discrimination method for RSS values and a self-adapting K value were presented.Confirmed by the experiments,the algorithm not only can find the effective similarity sample points completely,but also can eliminate the non-substantive similarities points,and then can adapt to the different scenes,then have the higher positioning accuracy.…”

    Adaptive spectrum sensing algorithm based on cyclostationary spectrum energy by Hao-ye ZHANG, Zhi-hua BAO, Shi-bing ZHANG

    Published 2011-11-01
    “…Focused on the characteristic of cyclostationary spectrum of signal and the spectrum sensing in low signal-to-noise ratio,an adaptive decision threshold spectrum sensing algorithm was proposed,which combines cyclostationary spectrum sensing with energy detection.By weighting the sum of probabilities of detection and false alarm,estimating the eigenvalues of the cyclostationary spectrum,the algorithm provides an adaptive decision threshold which could differentiate the primary signal from the background noise.The simulation results show that the algorithm could perform well in low signal-to-noise ratio and remove the effect of noise uncertainty on the spectrum sensing.It outperforms maximum-minimum eigenvalue and blind detection with 4dB and 8dB respectively in signal-to-noise ratio,and has robustness to different modulated primary signal.…”

    No-feedback rate control algorithm for Wyner-Ziv video coding by SONG Bin, YANG Ming-ming, QIN Hao, HE Hong

    Published 2011-01-01
    “…To avoid using feedback channel,an encoder rate control algorithm for Wyner-Ziv video coding was proposed.Firstly,using the target frame-rate and the target bit-rate,It could determine the bit allocation for each group-of-picture(GOP).According to the correlation between adjacent frames,the bit budget for a GOP were further allocated to key frame and Wyner-Ziv frames within the GOP by dynamically choosing quantization parameter and quantization matrices.Then,with refinement of correlation-noise model(CNM) parameter,different LDPC(low-density parity-check) check matrices might be chosen for each bitplane to control the encoding bitrate of Wyner-Ziv frame.Experimental results show that the difference between expected target bitrate and actual encoded bitrate is less than 0.57% using the proposed method,and compared with existing algorithm,average PSNR(peak signal-to-noise ratio) of decoded video quality can be increased by 1 dB.In addition,our algorithm slightly increases encoder complexity,and can be used in practice.…”
