Transmitting power detection device for mobile communication system

Abstract

The device comprises low frequency conversion unit (1), high speed AD converter (2), control and analysis processing unit (3), frequency synthesizer (4). With being processed by low frequency conversion unit (1), signal to be tested is converted to intermediate frequency, which is sent to high speed AD converter (2) for carrying out quantization. Inputting quantized signal into control and analysis-processing unit (3) obtains value of transmitting power. When power value relevant to other frequency is needed, the control and analysis processing unit (3) changes frequency of frequency synthesizer (4), which converts frequency to identical intermediate frequency. Power of the frequency is obtained after AD quantization and analysis processing. The invention rises precision for testing transmitting power of system and lowers step at testing point. Comparing with prior art, the invention overcomes disadvantages of low testing accuracy, meeting requirement of communication system.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a transmission power detection system of the mobile communication system. Background technique [0002] In mobile communication systems, especially WCDMA and CDMA systems based on Code Division Multiple Access (CDMA) technology, all users share the same radio frequency band by using the longest linear feedback shift register sequence (PN code). To other users, each user looks more like random noise, so the power of each individual user must be carefully controlled to ensure that each user can meet the minimum communication requirements without overpowering other users sharing the same frequency band. Unnecessary disturbance to users. That is to say, the management and control of all resources in the CDMA system are centered on the transmit power and total interference level of base stations and mobile stations in the system, and its fundamental goal is to reduce the interfere...
