Spectrum prediction algorithm in ISM band based on two-dimensional LMBP neural network by Xiaoyu WAN, Pan HU, Zhengqiang WANG

“…With the rapid development and application of short-range wireless communications technology，the electromagnetic interference of ISM（2.4 GHz）band has become more apparent.Using the spectral prediction algorithm to predict the information of spectrum occupancy has become an effective way to solve the problem of compatible coexistence between devices.On the basis of verifying the time-domain and frequency-domain correlation of ISM band，an LMBP neural network of time and frequency domain was proposed and applied in the spectral prediction of ISM band.Through simulations and theoretical analysis，the best training combination of time-frequency point （△t=5，△f=2）was obtained.This point improves 95% of the spectrum prediction accuracy under the conditions of the input vector N=9 of the neural network.It increased 9% and 4% prediction accuracy compared with Markov algorithm and time-domain LMBP neural network and it had a better convergence time of training.…”

Outage performance analysis for multi-UAV relay systems with threshold-based DF protocol by Zhenlei DAN, Xuewen WU, Jian OUYANG, Xiaoxiao WANG, Chenwei GU

“…The unmanned aerial vehicle (UAV) relay system has become a hot topic as an effective method for the remote transmission in wireless communications.By taking path loss into account,a relay cooperative transmission system model based on multiple UAVs was established firstly,and the maximum output signal-to-noise ratio (SNR) of the system with threshold-based decode-and-forward (DF) protocol was obtained.Then,by assuming that both the uplink and downlink experience Rician distribution,the closed-form expression for outage probability (OP) of the considered system with multiple UAVs was derived.Furthermore,the asymptotic OP formula at high SNR was also derived to show the diversity order and array gain of the considered system,which were convenient to reveal the effects of system parameters on the outage performance.Finally,the computer simulations verify the correctness of the theoretical analysis,and reveal the effect of the relay number,antenna number and the threshold on the system outage performance,thus the proposed scheme can provide guidance for the system design and application.…”
