The structure of triaxis fiber optic gyroscopes with frequency division multiplexing and frequency distribution characters of the system were introduced. The relationship among the output signal with modulation frequency and depth was focused on. The simulation results show that the output signal intensity of FOG presents the "hump" effect on condition that the modulation depth varies in a certain range. Then the modulation frequency and the depth of each fiber optic gyro can be optimized. And the cosine-modulated filter banks based on wavelet theory was designed to process the output signal of gyroscopes.
