Faced with the shortcomings of less computing resources and limited power supply of vehicle mobile terminals, mobile edge technology came into being. Firstly, a multi-terminal single-edge vehicle network model is established to alleviate the terminal pressure by accessing Multi-Access Edge Computing ( MEC ) servers. Aiming at the heterogeneous computing network, this paper constructs a joint optimization problem of task offloading and resource allocation under the constraints of delay and energy consumption. Aiming at the problem that the resources in the offloading decision process exceed the load, the modified chromosome and the improved elite selection strategy are used to optimize the genetic algorithm. The dynamic parameter adjustment strategy is used to optimize the particle swarm optimization algorithm to prevent premature convergence. A two-stage joint optimization algorithm is proposed to solve the problem. It can be seen from the results that the optimized algorithm can find the appropriate optimal solution and effectively reduce the cost compared with GAVECOS and Partial algorithm.","PeriodicalId":440430,"journal":{"name":"International Conference on Electronic Technology and Information Science","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115083327","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 polarization state of the transmitted signal is used to represent the communication information to realize the directional polarization modulation in the desired direction. The vector antenna is divided into two sub-arrays. Each sub-array is controlled by a different time sequence to turn on the antenna. The correlation between the horizontal and vertical components of the polarization signal is destroyed. The communication direction is not affected, but the desired polarization state cannot be synthesized in the non-communication direction. The simulation results show that the desired polarization state is received in the communication direction, the polarization information of the signal in the non-communication direction is disturbed, and the information leakage from the time-modulated array due to sideband radiation is avoided.","PeriodicalId":440430,"journal":{"name":"International Conference on Electronic Technology and Information Science","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117036519","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}

Based on the requirements of these circuits for power management chips, a fast-transient capacitorless low dropout regulator is proposed in this paper. To enhance the transient response, a push-pull buffer is added between the error amplifier and the power transistor. In addition, a transient enhancement circuit is used to effectively suppress the undershoot voltage and overshoot voltage and reduce the recovery time. The capacitorless LDO is verified in TSMC 180nm CMOS process. The simulation results show that when the load current changes from 1mA to 100mA within 1us, the output undershoot voltage is 83mV, and the recovery time is 1.5us; When the load current changes from 100mA to 1mA within 1us, the output overshoot voltage is 80mV and the recovery time is 1.7us. The power supply rejection of the whole system is -60dB at 1kHz and can still reach -17dB at 1MHz.","PeriodicalId":440430,"journal":{"name":"International Conference on Electronic Technology and Information Science","volume":"320 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127566340","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 addition, the proposed algorithm further increases the total network throughput of the NR-U system by combining spectrum resource allocation and transmission power, and improves the spectrum efficiency in both licensed and unlicensed bands.
