| description | Intelligent traffic system is one of promising technologies for traffic industry.Based on communication among cars, pedestrian, traffic infrastructure and cellular networks, it’s able to significantly promote on road safety and efficiency by making proper traffic instructions.How to precisely evaluate the communication performance of a whole vehicle become a hot-topic in the field.Unfortunately, there is still no solution about the setup and procedures for the OTA testing.A low-cost solution was proposed by reconstructing channel models and optimizing the existing testing system framework that referred to as multi-probe anechoic chamber.The proposed method was able to multiple the test area with limited channel emulator RF channels by introducing a low-cost digital converter.Numerical simulations indicate that the proposed method has the ability to reproduce spatial and temporal correlation features of the target channel model, which is coherent with related standards’ requirements. |
