In view of the demand location awareness in a special complex environment, for an unmanned aerial vehicle (UAV) airborne multi base-station semi-passive positioning system, hybrid solutions and optimized site layout system can effectively improve accuracy specific region. this paper, geometric dilution precision (GDOP) formula time difference arrival (TDOA) angles (AOA) algorithm is deduced. Mayfly optimization (MOA) which new swarm intelligence introduced, method to find optimal station UAV...
Location technology is playing an increasingly important role in urban life. Various active and passive wireless positioning technologies for mobile terminals have attracted research attention. However, signals experience serious interference high-density residential areas or the interior of large buildings. The main type that caused by non-line-of-sight (NLOS) propagation. In this paper, we present a new method optimizing angle arrival (AOA) measurement to obtain high accuracy location...
To satisfy the service requirements of high accuracy and efficient life detection location for search rescue (SAR) missions after a disaster, we developed passive positioning method to locate mobile phones by capturing random access preamble, which can be applied fourth-generation (4G) even fifth-generation (5G) communication systems. We analyzed characteristics procedure system established way detect combining time-difference-of-arrival (TDOA) estimation determine location. Then, performed...
We experimentally demonstrate the dual functionality of OFDM signals for both communication and sensing. Photonics-aided ISAC system in W-band achieves range-Doppler imaging with 0.0102m resolution data rate 48.04 Gbit/s over wireless link.
The principle advantage and shortcoming of quantum clustering algorithm (QC) is analyzed. Based on its shortcomings, an improved - exponent distance-based (EQDC) produced. It the iterative procedure QC used distance formula to measure between data points cluster centers. Experimental results demonstrate that accuracy EDQC outperforms QC, in process performs better than Euclidean preprocessing. What's more, IRIS dataset can come a satisfied result without
As an effective tool for three-way decisions (3WD) problems, decision-theoretic rough sets (DTRSs) have raised increasing attention recently. In view of the advantages q-rung orthopair uncertain linguistic variables (q-ROULVs) in depicting information, a new DTRSs model based on q-ROULVs is proposed to solve group decision-making (3WGDM) problems. Firstly, loss function depicted by and constructed subsequently. Secondly, aggregate different experts’ evaluation results (GDM) scenario,...
To satisfy the requirements of high-precision locating and life detecting after disaster, this paper proposes a passive positioning method for mobile phone by capturing preamble sequence which can be applied to 4G even 5G communication system. We analyze characteristics random access procedure system present way detect combining time difference arrival (TDOA) estimation solve location. Then we do experiment simulation acquisition, result proves that is feasible has high detection accuracy in...
The present study proposes a new algorithm for device‐to‐device (D2D) user density identification in 5G network based on resource allocation. method initially established multiobjective optimization function that calculates system throughput and quality of service (QoS) D2D users. optimal allocation result the is obtained via improved whale (IWOA). System after exhibits linear relationship with number Therefore, areas are accurately identified value. simulation reveals accuracy reaches 95%.
Abstract For the problems of privacy data protection caused by massive sharing in construction power Internet things, a sensitivity measurement and classification model based on information entropy BP neural network is proposed. Firstly, recognition matching algorithm proposed to identify sensitive level attributes dataset, used determine weight level, so as calculate value records dataset; finally, output results. The experimental results show that can achieve accurate data, with low...
Wireless communication channel model is very important in the indoor wireless and localization. Presently vector network analyzer (VNA) usually used as measurement system. There are some elements such cable antennas system which need to be calibrated, calibration method using electric free space test was given this work. The analyzation of focused on attenuation multipath delay. Because power-delay profile measured unclearly, With Anti - logarithmic transform, delay much clearer obtained. It...
