    Research on multi-target recognition method based on WSN and blind source separation by Pengju HE, Gangyi LIU, Siyi LIU

    Published 2019-03-01
    “…Aiming at the problem of signal aliasing in multi-target detection and recognition using wireless sensor network (WSN),a blind source separation algorithm was proposed,which can determine the number of targets and obtain the accurate source signals.In this algorithm,the multichannel mixed signal was used as the analysis object,the number of source signals was determined based on the eigenvalue method and then the blind source separation algorithm based on the non-negative matrix factorization was used to obtain the separation signals.The experimental results indicate that the number of targets can be determined and the accurate separation signals can be obtained by the proposed scheme.It can be applied to solve the problem of signal aliasing in multi-target detection and recognition.…”

    Error exponent for TAS/MRC fading channel by Changshui LI

    Published 2016-05-01
    “…Using Meijer-G function,exact expression for the random coding error exponent,ergodic capacity,cutoff rate,expurgated exponent of TAS/MRC Nakagami-m fading channel were derived.Numerical results show that the random coding error exponent is related to channel fading coefficient,coding rate,the number of transmitting and receiving antennas,and signal symbol period.With the coding rate,the number of the receiving and transmitting antennas and the average signal to noise ratio increasing,the RCEE of the system will become larger and the BER performance of the system will be better.For a given decoding error probability of a wireless communication system,necessary coding length,number of antennas,channel coherence time,and spatial fading correlation could be estimated by computing the random coding error exponent.…”
