Description
Summary:Aiming at the integrated control system of intelligent car and shore control center, revolving around high frequency wireless transmission control, this paper introduces the concept of maximum likelihood estimation (MLE), and proposes a power loss equation construction method of the intelligent car based on frequency domain transformation. Proceeding from frequency domain model, the influence of the corresponding parameters on path loss performance of received power which reaches the intelligent car is simulated and analysed in this paper. From simulation results of the frequency domain model, when the incident angle, α, is 0.4π, the corresponding received power path loss to the intelligent car is minimized. The result reflects the smallest received power path loss to the intelligent car and the impact on the system performance.
