Mobile Network Base Station Interaction Analysis Based On DSP

The technology of communication develops fast, especially the mobile communication. The mobile communication network becomes more and more complicated and draws more and more users, so the requirements of quality of network service gets higher and higher. It's obvious fact that signals in the space can cause interaction to the mobile communication network. These interacting signals damage the quality of calls by call missing, low call completing rate, which affects the quality of the whole network, hence to damage the reputation of the service provider. To solve the interaction problem, only by adopting scientific methods and proper tools can we search out the interaction source quickly. Combining DSP technology, AD conversion technology, computer interaction technology, GIS technology and Visual C++ technology, the paper researches into the interaction of base station of mobile communication based on the elementary algorithm and methods of software engineering. The system first uses DSP chip to compute the spatial frequency, transfer the date to background PC, then make out the graphic interface using Visual C++, and show the result of interaction analysis hence to implement the function of interaction analysis. The main outcomes of the paper are as follows: 1. Deep research into DSP technology and computer bus technology, design the hardware and circuit interface of PC and DSP. PC and DSP exchange data using high speed static RAM and bus arbitration circuit and corresponding handshake signal is designed to ensure the correct reading and writing RAM. 2. Use UML(Uniform Modeling Language) to do service modeling and demand analysis for the interaction analysis software system, and research into the architecture of the software . 3. Ensure that the system can implement real-time data exchange with DSP without point missing by researching into the methods with which the computer operate the I\O port of hardware and inner memory address. 4. Realize directional atlas analysis, intraband power analysis, sound warning, channel occupation analysis, especially the channel occupation analysis, which is not available in the kinds of spectrum interaction analyzers inland and overseas.
