In this paper, the hardware and software of the rate-biased platform are designed based on the preliminary study of the rate-biased technology, and experiments of laser gyro scale factor and random walk are conducted on the rate-biased platform.

Study on frequency deviation expansion methods for frequency modulated crystal oscillator;

Its function is to measure the frequency deviation of low frequency modulation.

The theoretical calculation of the primary electric parmeters,frequency deviation, distortion, frequency respond,signal-noise ratio of the FM transmitter is analysed, and the computer calculation of the automatic monitoring of these primary parameters and the rectifying method of the calculation error are also studied.

Optimal training signals for joint estimation of channel response and frequency offset in multiuser OFDM;

Performance comparison of achievable bit rate in FMT and OFDM system in the presence of frequency offset;

Analysis and simulation of the frequency offset influence on FMT system;

Influence of He-Ne Pressure on Biasing Value of Zeeman Laser Gyroscope;

The biasing effect of Zeeman laser gyroscope affected by He-Ne gas was studied theoretically and experimentally.

In wireless communication system, there is a large frequency bias between carrier frequency and local oscillating frequency.

Frequency estimator which based on two-order adaptive notch filter is the one frequently used for sinusoid on engineering,with a precondition that there is a small frequency bias of reference signal to input signal.

Two new methods of accurate measurement for frequency modulation deviation;
