Abstract

This invention provides an interference suppression equipment and method used in the wireless communication system, in which the said method includes the following steps: (1) the base station detects the uplink interference and the noise power; (2) based on the detection results, determine whether there is interference, and if interference and noise power over system tolerance threshold, there is interference; (3) if there is interference, the base station automatically adjusts its own receiving sensitivity; (4) by the closed-loop power control of the base station, adjust the terminal's transmission power. This invention can improve the system interference suppression capability, particularly more significant for the capacity upgrade and application environment expansion of the CDMA system whose system capacity is limited by itself interference restriction.

Description

technical field [0001] The invention relates to a device and method for interference suppression in a wireless communication system. Background technique [0002] Radio waves propagating in free space will be interfered by electromagnetic waves of different types of radio transmitters or high-voltage arc discharges and other electronic and electrical equipment. In the case of relatively strong interference, it will seriously affect the performance of the system. [0003] Therefore, it is necessary to suppress interference in a wireless communication system to improve the interference suppression capability of the system. Contents of the invention [0004] The object of the invention can be achieved by equipment comprising the following components: [0005] A base station antenna; [0006] A power splitter connected to the base station antenna; [0007] A baseband receiver / transmitter connected to the power divider; [0008] an analog-to-digital / digital-to-analog conve...
