The optical air data sensor in accordance with the present invention is an optical air data sensor, mounted on an aircraft, for emitting a laser light as a transmission light into atmosphere, and then receiving a laser scattered light produced by scattering of the laser light by aerosol present in the atmosphere as a reception light, thereby to measure an airspeed and a wind velocity of airflow in a distant region on the basis of a Doppler shift amount between the transmission light and the reception light, wherein a true airspeed is autonomously measured, without setting a reference velocity, by successively sweeping a frequency offset corresponding to a reference velocity for providing an offset to a measurement frequency, and performing this sweeping within a frequency range in which the Doppler shift amount is measured.

The demodulator of the invention includes a DSP. The DSP determines the distortion amount of the transmission channel based on known signals included in a radio receiving signal, and estimates the frequency of the direct wave based on the distortion amount. Furthermore, the DSP rotates the phase of the distortion amount based on the phase amount corresponding to the estimated frequency of the direct wave. Next, the DSP estimates the center frequency of the Doppler spread based on the distortion amount after the phase is rotated. Furthermore, the DSP synthesizes the phase amount corresponding to the estimated center frequency of the Doppler spread and the phase amount corresponding to the frequency of the direct wave to estimate the last frequency offset. Thereafter, the DSP eliminates frequency offset of the radio receiving signal based on the estimated frequency offset. Thereby, a sufficient frequency offset compensating range can be secured, and excellent BER characteristics can be realized.

Method and apparatus for automatic frequency control and demodulator

A transmitting side periodically inserts a known signal consisting of successive N symbols into an information signal consisting of (N &minus;N ) symbols and transmits the N symbol signal. The receiving side receives the N symbol signal, and automatically controls a frequency by estimating a frequency deviation from the incoming signal. More specifically, the receiving side outputs I and Q-channel analog baseband signals from the received incoming signal as well as from a sinusoidal signal outputted from an oscillator, and converts the analog baseband signals to the digital baseband signals. Then a phase difference for one symbol cycle is estimated from the digital baseband signals, integration processing is executed by iterative addition of the estimated values, and the frequency deviation is eliminated from the digital baseband signals using a result of the processing for integration.

The present invention aims to obtain a demodulator with improved receiving performance such as bit error rate characteristic by reducing the estimation error of the fading distortion even in case of transmitted signal in the channel which is much influenced by not only fading variation but also the thermal noise such as in the nonfading channel. In the demodulator of the invention has a configuration where the carrier is estimated using the known signal to perform the coherent detection. In the carrier estimator, the fading distortion estimator obtains a predetermined form of the estimation of the fading distortion using the known signal, the fading distortion compensator eliminates the fading distortion estimated from the received signal by a predetermined compensating method. The averaging unit obtains the average value of the compensated signal, of which the modulation component was eliminated from the output of the fading distortion compensator. The estimated signal generator compounds the averaged value output from the averaging unit and the estimated value of the fading distortion output from the fading distortion estimator to obtain the reference signal. The signal compensator performs the coherent detection using the reference signal obtained by the estimated signal generator.
