Design of Mobile Communication Non Intersymbol Interference System based on Calman Filter and PID Control

摘要

In the digital baseband transmission system, the intersymbol interference is one of the main factors affecting the performance. Therefore, how to overcome its influence, making the system error rate reduction must study and solve the problems in the digital baseband system. This paper designs a new mobile communication non intersymbol interference filtering system based on MATLAB numerical simulation, the system is the integration of the Calman filter theory, and combining the genetic algorithm and PID control algorithm to achieve the rapidity and stability of the system filter. The filter design and validation simulation can be seen that the filter can effectively eliminate the measurement and observation error in the mobile communication process, to avoid the signal fluctuation caused by intersymbol interference. Through the system response curve, it can be seen that the system does not appear overshoot, fast convergence speed, and good response stability will provide the technical reference for the research of mobile communication system.
