MATLAB中提供了汉明码的编解码、4FSK调制解调函数和不同通信信道模型函数，本程序直接调用进行编程。借助于MATLAB可大大地拓宽研究分析的视野提高研究设计的效率,具有重要的推广和应用价值。 (MATLAB provides the hamming codec 4FSK modem function and different communication channel model function, the program calls directly programming. Help of MATLAB can greatly broaden the horizons of research and analysis to improve the efficiency of the study design, with promotion and application value.)

Hi I like to integrate GPS and INS using kalman filter to predict the position of a vehicle. first of all i like to use GPS sensor readings with kalman filter . I have read lot of research papers for that purpose but I donot know how to use real time data of GPS sensor in the kalman filter measurement equation. My question is that where i have to put the readings the gps sensor in measurement equation i.e where to put numerical values the sensor in the measurement equation.how these values make sense. zk=Hxk+wk also i like to ask as how can i determine the state transition matrix F and observation matrix H for a particular application. also how can i determine the measrement noise matrix the gps sensor. thanks and regards
