To overcome the problem of spectrum scarcity, the massive number of machine-type devices (MTDs) are allowed to reuse the spectrum resource allocated to the cellular users (CUs) opportunistically. However, the complicated interference caused by channel reusing and the energy efficiency issues pose new challenges on resource allocation. In this paper, we investigate the problem of energy efficiency maximization for MTDs via jointly optimizing channel selection and power control. At first, each MTD is temporally allocated with a predefined transmission power. Next, the channel selection optimization problem is solved by matching with externalities to derive the matching relationship between MTDs and resource blocks (RBs). And the power control optimization problem is solved by the nonlinear fractional programming algorithm. Simulation results demonstrate that the proposed algorithm outperforms the other two heuristic algorithms distinctly.","PeriodicalId":306112,"journal":{"name":"2019 IEEE 19th International Conference on Communication Technology (ICCT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122615145","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}

The design of inter-domain and intra-domain routing protocols in regional routing protocols has a huge impact on network performance. Due to the large overlap of intra-domain area of hybrid routes, large routing overhead and repeated pathfinding between domains, this paper improves the intra-domain routing mechanism and intra-domain routing mechanism of the traditional ZRP protocol based on the large-scale wireless ad hoc network of high-speed mobile scenarios. Different from other protocols to optimize the routing mechanism itself, this paper will establish a multi-center intra-domain routing area based on the neighbor connection degree in order to greatly reduce network overhead. And it establishes adaptive routing based on link quality in the inter-domain routing mechanism. This paper analyzes the performance of the improved routing protocol NA-ZRP through NS2 simulation. The results show that the NA-ZRP protocol can better adapt to the large-scale high-speed mobile wireless ad hoc network scenario than the traditional ZRP.","PeriodicalId":306112,"journal":{"name":"2019 IEEE 19th International Conference on Communication Technology (ICCT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127691698","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}

General object detectors are prone to miss detection and Confuse the roof of the car with the roof of the house in aerial image. Therefor we improved YOLOv3 in order to resolve the task of vehicles detecting.

However, the existing compressive sensing recovery algorithms with unknown sparsity often require noise power or signal-to-noise ratio (SNR) as the priori conditions, which greatly reduces the algorithm adaptability in multi-user detection. Therefore, an algorithm based on cross validation aided structured sparsity adaptive orthogonal matching pursuit (CVA-SSAOMP) is proposed to realize multi-user detection in dynamic change communication scenario of channel state information (CSI). The proposed algorithm transforms the structured sparsity model into a block sparse model, and without the priori conditions above, the cross validation method in the field of statistics and machine learning is used to adaptively estimate the sparsity of active user through the residual update of cross validation. The simulation results show that, compared with the traditional orthogonal matching pursuit (OMP) algorithm, subspace pursuit (SP) algorithm and cross validation aided block sparsity adaptive subspace pursuit (CVA-BSASP) algorithm, the proposed algorithm can effectively improve the accurate estimation of the sparsity of active user and the performance of system bit error ratio (BER), and has the advantage of low-complexity.","PeriodicalId":306112,"journal":{"name":"2019 IEEE 19th International Conference on Communication Technology (ICCT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128442052","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}

Under the condition that the BER performance does not decrease, only the original 1/N memory requirement is needed (where N is the number of master interleavers) can achieve the low computational complexity of $log_{N}K$ (K is the number of user accesses).

In the considered model, the primary transmitter communicates with the primary receiver with the aid of an amplify-and-forward (AF) relay by transmitting OFDM-IM signals. Meanwhile, the secondary transmitter passively senses the spectrum and transmits its own information over those inactive subcarriers of the primary network to the secondary receiver. Through the proposed protocol, inactive subcarriers inherent in the existing OFDM-IM systems can be fully exploited, thus improving the spectral efficiency. To evaluate the performance, closed-form upper bounds on the bit error rate (BER) are derived for both users utilizing the optimal maximum-likelihood detection. Simulation results corroborate the analysis and show that the proposed scheme has the potential of outperforming OFDM-IM-AF in terms of BER with higher spectral efficiency.","PeriodicalId":306112,"journal":{"name":"2019 IEEE 19th International Conference on Communication Technology (ICCT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115789733","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}
