If receivers have independent feedback channel, it will waste a lot of frequency or time slot resources. Whereas, if all receivers share the same channel to transmit feedback message, a feedback storm will occur, which causes the transmitter to be unable to confirm which receiver has successfully received the information packet. In order to make use of receivers feedback message, in this paper, we propose a novel fountain codes based on superposition feedback. By analyzing the intensity of received superposition feedback signal, the probability of information packet can be recovered by all receivers is calculated, which can be used to adjust the selection probability of information packets. Simulation results show that the proposed fountain codes in broadcast scenario can significantly reduce the overhead compared to traditional fountain codes.","PeriodicalId":263098,"journal":{"name":"2022 IEEE 8th International Conference on Computer and Communications (ICCC)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116540748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some studies have shown that wind farms interfere with weather radar and air traffic control surveillance radar. The radar echo signal of fast-rotating wind turbine blades has a wide Doppler spectrum, and the general radar clutter processing methods cannot remove wind turbine clutters with such characteristics, which interferes with the target detection performance of nearby radar equipment seriously. The study of statistical characteristics of the echo signal of wind turbines could provide basis for detection, recognition, elimination of wind turbine clutters. This paper provides statistical models of radial velocity and spectrum width for wind turbines based on Level II data of the WSR-88D weather radar. The orientation of blades' rotation plane has impact on statistical analysis result. In order to solve this problem, we employ the wind direction information to estimate the orientation of blades' rotation plane and we analysis the statistical characteristics in some particular orientation. The real data are utilized to obtain the empirical probability density function and then different probability density functions are used to fit the empirical probability density function. The K-S test and root mean square error are employed to compare the performance of different statistical models. Through the statistical analysis of four different types of wind turbine, the preferable statistical model for radial velocity and spectrum width are obtained.","PeriodicalId":263098,"journal":{"name":"2022 IEEE 8th International Conference on Computer and Communications (ICCC)","volume":"177 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115302923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such cases, the majority class dominates the deep learning training, which changes the decision boundary of the minority class and reduces the classification accuracy. In this paper, we propose a novel location-based scene reconstruction(LSR) data augmentation method for long-tail recognition. This approach uses a gradient localization method to increase the scenes of tail class samples and enhance the discrimination of the model between head and tail classes, thus the accuracy of long-tail recognition is improved. Experiments on two benchmark datasets show that the LSR method achieves state-of-the-art performance on the long-tail recognition task.

We first discuss the workflow of the proposed scheme, and then restore the impaired Markovianity due to the introduction of subthreads by enhancing the state space in MRP.

The CDR is implemented in a type-II bang-bang phase-locked loop (BBPLL) topology. To reduce the locking time and improve the stability of CDR, all of the PAM4 signal transitions with the central crossover point chosen by a waveform filter are utilized to extract the phase error.

By building a multi-objective optimization problem aimed at maximizing the satellite battery life and minimizing the end - to-end delay and packet loss rate. Satellite network routing is considered as a Markov Decision Process (MDP), while combining deep learning with reinforcement learning to learn a routing strategy by utilizing the former's powerful perception capability and the latter's decision making capability to balance the inter-satellite battery usage and reduce the satellite battery cycle life consumption.

Some existing channel access methods require exchanging information between unmanned aerial vehicles (UAVs), while others consider only one type of interference. In this paper, we study the problem of distributed channel access in the FANET with limited channel resources, where internal co-channel interference and external malicious interference are considered. A non-cooperative game is designed to characterize the interaction between UAVs. We prove that the proposed game is an exact potential game, which guarantees at least one pure strategy Nash equilibrium (NE). We propose a distributed channel access algorithm based on the stochastic learning automata. By independent strategy updates, UAV s can quickly achieve global convergence under different interference scenarios.
