This paper explores timing synchronization algorithms for high-order 64-APSK signals. First, the applicability of two commonly used timing synchronization algorithms for higher order 64-APSK signals, the Gardner algorithm of feedback structure and forward structure algorithm based on the digital square ring are studied in this paper. And then, through the analysis of these two algorithms with the characteristics of higher-order APSK signals, an improved idea of eliminating high-order influence in timing synchronization algorithm is obtained.","PeriodicalId":332213,"journal":{"name":"2018 International Computers, Signals and Systems Conference (ICOMSSC)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127301359","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}

Aiming at the reliable adsorption problem of biped wall climbing robot, a torque optimization method based on genetic algorithm is proposed. Based on the analysis of the relationship between the adsorption load and the reliability index, the adsorption reliability and the compliance index are taken into account and the genetic algorithm is used to get the global optimization solutions so as to achieve comprehensive optimization. The simulation and analysis of the proposed method are carried out, and the prototype experiments are conducted in the simulated environment of vertical steel wall in the lab.

Therefore, combining with Canny operator to detect the edge of radar scanning image, an improved radar image interpolation algorithm is proposed. Finally, experiments are conducted and compared with the nearest neighbor interpolation algorithm, bilinear interpolation algorithm and FEOI algorithm. The experimental results show that the proposed algorithm is superior to the above algorithms and can effectively reduce aliasing and blurring and obtain the interpolated image with good visual effect.

This paper presents a method to estimate human voice fundamental frequency in polyphonic music signal using tandem filter. There are three-stage filters in this method. At first stage, it’s easier to extract human voice fundamental frequency if a singing voice separation preprocessing is obtained. This paper uses the robust principal component analysis to roughly extract the human voice from polyphonic music signal. At the second stage, it is believed that although the human voice spectrogram is reserved and the accompaniment effect is reduced, there is still noise or false fundamental frequency. Thus, a hyper-Fourier Transform is implemented to lower the noise. At the third stage, the STFT spectrogram have the original information of the melody frequency structure. So this paper uses a transverse stripe filter system to eliminate the non-possible fundamental frequency position.","PeriodicalId":332213,"journal":{"name":"2018 International Computers, Signals and Systems Conference (ICOMSSC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129721350","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 this paper, a novel lightweight hash function DLDL is proposed, which is based on the sponge construction and PRESENT-like internal primitive. A small scale linear diffusion layer is added in PRESENT to increase the confusion of linear diffusion layer with few hardware cost. Besides, the paper analyzes the security of holistic and internal primitive and designs the multiplexing scheme of 3-bit S-box, moreover, it provides the hardware implementation of DLDL and compares with other analogous lightweight hash functions. The experimental results indicate that DLDL is close to PHOTON but a little lower than SPONGENT in terms of security. However, DLDL evidently achieves less cost than SPONGENT and PHOTON in hardware implementation.","PeriodicalId":332213,"journal":{"name":"2018 International Computers, Signals and Systems Conference (ICOMSSC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123590892","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}

Due to the backroom effect, the products with higher freshness are periodically replenished from backroom to shelf, where freshness-and-shelf level-sensitive consumers purchase the products according to their \"perceived average freshness\" of displayed fresh products. Based on the analysis of dual-sensitive demand, this paper formulates the functions of \"consumer perceived freshness\" and inventory level on both shelf and backroom. Then it develops the decision-making model including shelf replenishment period and reorder point, and the neighborhood search algorithm is designed to solve this model. Finally, it conducts groups of numerical examples revealing the impact of the backroom effect on the retailer's optimal order quantity, shelf replenishment period, and reorder point (stock level when ordering from suppliers). The main results show that retailers who ignore the backroom effect will miss out on market share and profit margins. When the retailer realizes the existence of the backroom effect, he should increase the order quantity to obtain a higher profit value.","PeriodicalId":332213,"journal":{"name":"2018 International Computers, Signals and Systems Conference (ICOMSSC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125413617","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}
