摘要： A first radar transmitter and a second radar transmitter transmit a first modulation signal and a second modulation signal which are generated by repeating a predetermined time of code sequences, each of which has a predetermined code length, using a first code width and a second code width, respectively. An A/D converter converts the modulation signal into a discrete signal in a sampling cycle shorter than a difference between the first code width and the second code width. A positioning section separates a plurality of reception signals using a first correlation value based on outputs from the A/D converter and a first delay section corresponding to the first code width and a second correlation value based on outputs from the A/D converter and a second delay section corresponding to the second code width.

摘要： The disclosed technique includes transmitting a signal intermittently according to a transmission cycle having a predetermined transmission period and a non-transmission period; receiving the signal reflected from a target with reception antennas; and detecting the target from the reflected signal. A high-frequency transmission signal attenuated during the transmission period and a receipt signal received during the non-transmission period are combined together. A correlation value between a reference transmission signal and the receipt signal in the combined signal is calculated, and the amount of phase shift in an arbitrarily selected reception antenna is calculated from the correlation value of a reference reception antenna, and the correlation values of the other reception antennas. The phase component of the correlation value of the arbitrarily selected reception antenna is corrected on the basis of the amount of phase shift.

摘要： A communication system has a base station control device and base station devices. The base station control device totalizes information on the number of base stations as the number of base station devices which can communicate with a mobile station device, makes Nb copies of a data frame, successively assigns integer values from 1 to Nb as stream numbers Ns to the data frames copied, and forms Nb copied data frames including Nb and Ns in header information. Copied data frames having different Ns in the header information are sent to base station devices. According to Ns and Nb, a base station device subjects the data in the copied data frame to temporal/spatial encoding to form a temporal/spatial encoding series. A mobile station device receives the temporal/spatial encoding series signal from each of the base station devices.

摘要： A spatial filtering adaptable for an interference wave that appears unsteadily can be implemented and also an interference canceling ability can be increased even in a condition that the interference wave does not steadily exist. At a time of non-active communication, the signals from a plurality of interference source radio communication devices 2 are received in advance by an interference signal receiving section 6 as the pre-process mode, then a resultant interference correlation matrix RI is stored in a storing section 7, and then an interference wave receiving antenna weight WI used to receive selectively the transmission signals from the interference source radio communication devices 2 is prepared based on the resultant interference correlation matrix RI. At a time of communication, the operation goes to the receiving process mode to normally receive the signal by a signal separating section 9, and a variation of the interference wave component is detected by an interference wave level detecting section 8 based on a signal power received using the interference wave receiving antenna weight WI. When the interference wave appears or changes, a desired wave separating/receiving antenna weight used to reduce the interference by using a new interference correlation matrix is changed adaptively.

摘要： A pulse signal is produced in a pulse generating section, and repetitively transmitted from an antenna at constant time intervals. A reception signal, received through an antenna and including a reflective wave from an object, is amplified and gain-adjusted. Thereafter, a distance detecting section detects a reception pulse of the reflected wave, and calculates the distance to the object. The variable attenuator attenuates the reception signal by a gain adjusted in accordance with a gain control signal. The gain of the variable attenuator is controlled so as to be maximum immediately after the pulse signal is transmitted, and to be reduced with elapse of time. Based on a gain adjustment timing signal, a gain adjustment timing when the attenuation amount is changed is made different for each transmission of the pulse signal.

摘要： Wireless communication apparatus adopting a time division duplex system for transmission and reception using plural antennas, deviation of amplitude and phase occurring between transmission and reception circuits is detected and corrected using a communication signal. Channel estimation means detects channel information based on reception output of N reception circuits having a one-to-one correspondence with N antennas. Correction value detection means finds a correction value for correcting deviation occurring between each of N transmission circuits and each of the N reception circuits based on the channel information. A wireless communication apparatus transmits an already known signal (training signal) to a base station with which the wireless communication apparatus conducts communications. The base station executes channel estimation based on the already known signal and generates and transmits a correction signal (probe signal). The correction value detection means of the wireless communication apparatus detects the correction value using the correction signal.
