With the rapid development of Internet of Vehicles, computing-intensive and delay-sensitive applications are widely used. 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.

In this paper, a directional polarization modulation method based on a time-modulated vector array is proposed for secure communication. 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.

As a basic module of integrated circuits, LDO is widely used in digital-to-analog and analog-to-digital conversion circuits. 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.

Spectrum is a scarce and non-renewable resource. This paper proposes an improved adaptive spectrum access mechanism for unlicensed millimetre waves, which is based on the problem of low spectrum utilisation due to the high signalling overhead of the receiver-assisted Listen Before Talk (LBT) mechanism. By introducing an adaptive duty cycle to the receiver-assisted LBT frame structure, the system parameters can be adaptively adjusted to ensure that New Radio-based Access to Unlicensed Spectrum (NR-U) and Wireless Gigabit (WiGig) The two systems can coexist in a fair and harmonious manner. 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. Simulation results show that the proposed mechanism is significantly better than the receiver-assisted LBT ones.

Due to the continuous and rapid expansion of the scale of the communication network, the deepening of the isomerization of the communication equipment in the network and the impact of network security factors, large-scale communication networks need to have a certain fault-tolerant mechanism to maintain connectivity for a long time. This paper studies faulttolerance from the perspective of structural statistics of communication networks. By studying how to make communication networks remain connected when some nodes fail, we can get the relevant laws, and provide the basis for highly reliable communication network deployment and the robustness of routing protocol design.
