Embodiment 1
[0048] figure 1 It is a schematic diagram of the cell structure adopted by the interfering and interfered mobile communication system provided by the present invention. The cell of the mobile communication system provided by the present invention is a regular hexagonal cell structure using an omnidirectional antenna.
[0049] It is assumed that the mobile communication system A is the interfered system, and it is the system that requires system performance evaluation. Mobile communication system B is an interference system. Both systems use a regular hexagonal cell structure with omnidirectional antennas, such as figure 1 shown. For the clarity of the diagram, only one base station is shown in mobile communication system B, which is represented by a solid triangle in the figure, while the base station of mobile communication system A is represented by a hollow triangle.

A rapid evaluation method for the anti-interference performance of a mobile communication system, comprises the steps of determining the path loss and the transmitting power from various mobile users in a single mobile communication system to a base station; determining the capacity value of a cell of the single mobile communication system without the interference of other mobile communication systems; determining the capacity value of the mobile communication system when the interference exists among the mobile communication systems; and comparing the capacity values of the observed base station of the interfered system under the condition that whether other interference systems exist or not, so as to determine the anti-interference performance of the base station in the interfered system, namely the anti-interference performance of the interfered system. The invention provides the rapid evaluation method for accurately and rapidly determining the anti-interference performance of the mobile communication system, and according to the method, the anti-interference performance of the system can be tested and judged scientifically. The rapid evaluation method has a broad application prospect in the aspect of analyzing the coexisting anti-interference performance of all the mobile communication systems, thereby having great significance of production practice.
Description
technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a test system and method for evaluating system anti-interference performance in a mobile communication system. Background technique [0002] At present, the main technical standards of the third mobile communication in the world are WCDMA, CDMA2000 and TD-SCDMA. These three technical standards are commercially available in China. China Mobile operates the TD-SCDMA network, China Telecom operates the CDMA2000 network, and China Unicom operates the WCDMA network. When different communication system networks operate in the same area, there will be problems of mutual interference between systems. [0003] In recent years, with the rapid development of the economy, the number of mobile communication users has also increased continuously. In order to cope with the sharp increase in the number of users, the network construction of the mobile communication sys...
