This scheme is an integrated communication scheme of IVC(inter-vehicle communication) and RVC with basestations at intersections. In conventional research, the performance analysis of this scheme is carried out by traffic and communication simulation, but the computational complexity of communication simulations is much larger than that of traffic simulations. For the reduction of the complexity, we derive the transmission success ratio and the required bandwidth theoretically and evaluate the performance using a traffic simulation and the derived theory. The performance comparison between this evaluation without communication simulations and the evaluation using both traffic and communication simulations shows that the performance evaluation of this scheme's RVC can be carried out without communication simulations. Moreover, we derive the optimum transmission frequency that minimizes the required bandwidth. As a result, the required bandwidth can be reduced by half under the same traffic situation.","PeriodicalId":143706,"journal":{"name":"2012 12th International Conference on ITS Telecommunications","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115090972","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}

Meanwhile, as the development of advanced cellular technologies, more than one component carrier (CC) can be jointly utilized in a base station (BS). As a result, the energy consumption of the BS has become an important concern. In this study, we thus propose a novel efficient power-saving scheme for the BS transmission to address the problem of the power minimization at BS transceiver subject to certain quality-of-service and fairness requirements for users. For this scheme, it is able to dynamically activate/deactivate CCs to utilize only the necessary power to enable energy-efficient data transmissions with the efficient control of the user fairness. In our model, activities in downlink data transmissions of a BS with multiple OFDMA-based CCs are considered, while concurrently supporting different types of users. Numerical results show that the total power consumption of our proposed scheme is significantly better than that of the case in which all CCs are always active when the traffic load is relatively light.","PeriodicalId":143706,"journal":{"name":"2012 12th International Conference on ITS Telecommunications","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116876876","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}

But these processes often increases the complexity of the hardware and software. In this system, we propose a VLSI implementation of image-based lane departure warning system. It is not only the gradient calculation of the lines and discrimination out of the lane line, but also real-time analysis of vehicle tires with the left and right side of the lane markings distance through the image of the video, and then judge whether the car lane offsets phenomenon. This system has been implemented in the Xilinx Spartan6 FPGA platform. It is using total 32% of logic resources, and it doesn't use SRAM or SDRAM. Its average recognition rate is 95%, the image frame rate 30 frames / s, and proceed forthwith back-end design with logic synthesis and Auto Place & Rout (APR) processing. This chip uses 0.18 um standard cell process. This system's core area is 1.47* 1.47 mm2, and core utilization is 0.8, sequential cell occupy 40% and frequency up to 100 MHz. This chip has advantages of low cost, small size and low power more than DSP or FPGA. It will be also more suitable to use in vehicle applications system, without external memory.","PeriodicalId":143706,"journal":{"name":"2012 12th International Conference on ITS Telecommunications","volume":"75 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128063453","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}
