An interference signal generation device for car self-organization network

Abstract

The invention relates to a car self-organizing network interference signal generator which consists of a channel selection and control module, an MAC unit and a baseband processor, an I / O modulation demodulation, an intermediate frequency (IF) and radio frequency (RF) processing unit, an antenna, etc. A bus interface adopts a USB pattern. The invention has three selective operating methods, each operating method can utilize a control module or a control program to realize the control on the channel scanning, thereby achieving the channel selection function and the power adjustment function. The generator can send out a physical signal according to the standards stipulated by IEEE802.11b. The invention has good practicality and programmability, and belongs to the inter-vehicle networking communication field, thereby being suitable for the testing of an inter-vehicle communication system.

Description

technical field [0001] The invention belongs to the field of inter-vehicle networking communication, and provides a vehicle ad hoc network interference signal generator, which is mainly used in the performance test of the vehicle terminal based on the ad hoc network in the networking communication. Background technique [0002] In the ad hoc network vehicle communication system, it is required that the vehicle communication terminal can maintain good communication quality in various possible communication environments. However, due to the high-speed movement of each vehicle and the influence of the actual communication environment, the inter-vehicle communication signal will be interfered and lost, which will affect the communication. Therefore, it is necessary to test the communication quality between vehicles in various environments. However, the cost of testing in the actual environment is high, the environment is uncontrollable, and the general-purpose signal generator i...

Problems solved by technology

However, due to the high-speed movement of each vehicle and the influence of the actual communication environment, the inter-vehicle communication signal will be interfered and lost, which will affect the communication. Therefore, it is necessary to test the communication quality between vehicles in various environments.

However, the cost of testing in the actual environment is high, the environment is uncontrollable, and the general-purpose signal generator is expensive, large in size, and complicated to use, which is inconvenient to use in the test of the vehicle ad hoc network communication system
