摘要： PROBLEM TO BE SOLVED: To provide a signal processor of a time-division multiplex adaptive array-antenna in which power loss can be minimized when changing over a switch, and deterioration of reception characteristics can be made less likely to occur.SOLUTION: In a time-division multiplex adaptive array-antenna 1, one reception circuit 4 is shared by multiple antennas 2. When connecting specific one of the multiple antennas 2 with the reception circuit 4 by means of one specific switch 6, power loss can be minimized during changeover of the switch 6 by prolonging the ON time thereof. Reception signals of respective antenna 2 are mixed when the ON time of the switch 6 is prolonged, but a sample signal x(t) is separated into reception signals of respective antennas 2, by subjecting the sample signal x(t) to operation of multiplying a matrix in an arithmetic processing unit 16.

SOLUTION: In the car sharing system, when an operation button 11 of a portable terminal 1a is operated by a user, the value of a key-side rolling counter is updated, and a locking/unlocking signal containing the value of the rolling counter is transmitted to an in-vehicle device 20. In the in-vehicle device 20, the value of the key-side rolling counter contained in the locking/unlocking signal is compared with the value of a vehicle-side rolling counter stored therein, and the door lock is licked or unlocked based on the comparison result. When the user makes a reservation for rental of the vehicle, the value of the key-side rolling counter stored in a database 32 of a management server 3 is transmitted to the portable terminal 1a. When the user applies for return of the vehicle, the management server 3 acquires the value of the key-side rolling counter stored in the portable terminal 1a and stores it in the database 32.
