摘要： PROBLEM TO BE SOLVED: To provide a device for horizontally spreading a sensor array without depending on the force of wind or drift current. SOLUTION: When a cable anchor mechanism 3 stops feeding of a suspended cable 2, the fall of a holding bracket 4 stops to separate a vessel 5, and a wing 5a provided at the vessel 5 spreads. When the wing 5a spreads, the vessel 5 begins to fall downward obliquely while feeding the sensor array 3. Once the cable anchor mechanism 3 has restarted feeding of the suspended cable 2, the holding bracket 4 falls vertically. The falling rate of the holding bracket 4 is braked by a drag body 9. As a falling rate is made about the same of vertical direction component of vessel 5' s oblique falling, the fed sensor array 3 is spread in horizontal direction.

摘要： PROBLEM TO BE SOLVED: To inexpensively provide the carrier signal local oscillator of a moving station by adjusting the frequency of the carrier signal local oscillator in accordance with the update quantity of a frequency and setting it to be equivalent to a system which continuously transmits a reference signal that does not execute data modulation. SOLUTION: When the symbol correlation value of the output of a correlation operation part 5 is in a known data section, the complex conjugate value of a known data value is multiplied and the complex conjugate value of the hard judgment value of data in the case of an information data section by the symbol correlation value of the output of the correlation operation part 5. The update quantity of the frequency is operated based on a channel estimation value being the output of a multi-path channel estimation part 2. The frequency of the carrier signal local oscillator is adjusted in accordance with the update quantity of the frequency being the output of a frequency update quantity operation part 3. Consequently, the oscillator becomes equivalent to the system which continuously transmits the reference signal that does not execute data modulation and detection is realized even if a carrier frequency error between the base station and the moving station is large.

摘要： PROBLEM TO BE SOLVED: To uniform the quality of communication and to improve the efficiency of the whole system by calculating communication quality at the discrete time based on the total power of received signals and the average of the received power of incoming information signals, and adjusting the number of mobile stations while increasing the number of mobile stations to be managed when the communication quality is excessive and reducing the number of the mobile stations to be managed when the communication quality is bad. SOLUTION: A total receiving power observing part 2 observes and outputs the total power of signals received at the time of discretizing (i). An information signal receiving part 3 calculates the average of the received power of the upward information signal transmitted from each mobile station at the time of discretizing (i) to output as a signal power S. A communication quality arithmetic part 4 calculates the quality of communication at the time of discretizing (i) based on the total received power outputted by the part 2 and the signal power S outputted by the part 3. The transmission power of a pilot signal is controlled based on this quality of communication. Namely, when the communication quality is excessive, the transmission power is made large to manage a part of the mobile stations under management by an adjacent base station.

摘要： PROBLEM TO BE SOLVED: To obtain code constitution capable of matching the constitution of demodulators in both of a mobile station and a base station, to use a spreading code for improving characteristics by synchronization for channels to be synchronized, to prepare plural codes sufficiently corresponding to the number of users, and to easily attain frame synchronization. SOLUTION: An initial value generated from an initial value generator 41 is applied to a user code generator 42. The generator 42 outputs a user code S42 to a counter 43 and a computing element 61 based upon a chip clock CK2. A code number generated from a code number generator 51 is applied to a channel identification(ID) code generator 52. The generator 52 outputs a channel ID code S52 to the computing element 61 based upon the chip clock CK2. The element 61 synthesizes both the codes S42, S52 and outputs a 3rd spreading code S61. A spreading part 13 diffuses user data UD based upon the code S61.

摘要： PURPOSE: To improve the accuracy of a propagation path estimation value by suppressing a noise without using a time average at the time of finding out the estimation value. CONSTITUTION: This propagation path estimator is constituted of a 1st correlator 13a for outputting a complex correlation signal (β.exp (jϕ)+N2) defined by the correlation values of a 2nd diffusion code sequency with the in-phase component and orthogonal component of a received base band respectively as a real number part and an imarginary number part and a low pass filter 13b to which the complex correlation signal is inputted. Since the frequency characteristics of amplitude β and a phase in a propagartion path estimation value (β.exp(jϕ)) are suppressed by maximum Doppler frequency and the frequency band of a noise (N2) is higher than the estimation value, the complex correlation signal is inputted to the low pass filter 13b having the frequency characteristic of fixed delay at the fixed amplitude up to the maximum Doppler frequency to remove or suppress the noie (N2) without exerting influence upon the characteristics of the propagation path. Consequently an accurate propagation path estimation value can be obtained.
