However, the computational complexity of the linear detector remains high due to the significant vast matrix, especially with the growing number of antennas and the user. Therefore, some strategies have been adopted to approach linear detectors to reduce complexity, but among previous research just focused on one linear detector. We utilize the singular value decomposition based on MMSE or ZF detector (SVD) and propose two algorithms to update and update the channel matrix SVD. The proposed update algorithm for the case when one user is attached to the base station. Golub Kahan and Reinsch, Gram Schmidt and Householder transform recursively to approach the diagonal matrix of singular values. This shows through simulation results that the proposed scheme exceeds the conventional scheme with reduced complexity and error 1-5%.","PeriodicalId":319683,"journal":{"name":"2019 6th International Conference on Information Technology, Computer and Electrical Engineering (ICITACEE)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128943829","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}

There is some jargons mention that more antennas used in amplitude comparison RDF will improve the RDF accuracy. However, a further analysis and real test is still required to support this argument. Therefore, this paper will verify this specific problem by develop 6 antenna RDF system and 4 antenna RDF system then analyse the real test data. A type of printed circuit board log-periodic dipole array (PCB LPDA) antenna is utilised in this paper for the experiment setup. The real test setup and the data collection is explained in this paper to discuss and verify this argument. After the discussion, it is verified that amplitude comparison with 4 antennas has better accuracy than the similar system with 6 antennas.","PeriodicalId":319683,"journal":{"name":"2019 6th International Conference on Information Technology, Computer and Electrical Engineering (ICITACEE)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129664414","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}

They still use hard robot technology made from rigid material. Hard gripper will be difficult when it is used to grasp and hold fragile objects such as eggs or grapes. Recently, many engineers and scientists who work in robotics in the world have developed soft robot technology that is applied to the gripper. In this paper, we present the development of three-fingered soft robotic griper based on pneumatic networks. Soft robotics fingers are manufactured using elastomeric material; silicon rubber (RTV 52). Soft finger molding material is produced using Polylactic acid (PLA) material and printed using 3D printer. The gripper can perform in a positive and negative pressure room. The actuator utilized in the soft robotic gripper is a mini air compressor. The performance of the proposed soft robotic gripper is tested for various grasping objects from hard to fragile objects in positive and negative pressure. Based on the test result, the developed soft gripper can take and grasp hard and delicate objects that have a mass less than 500 gr under positive pressure.","PeriodicalId":319683,"journal":{"name":"2019 6th International Conference on Information Technology, Computer and Electrical Engineering (ICITACEE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126502574","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}
