IPC: B60R25/10
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To prevent duplicate registration in addition to preventing registration work from being terminated in the state of not meeting the required number of registration due to misapprehension of a worker in case of registering a plurality of codes by informing the number of registration at the time of registering the codes. SOLUTION: At the time of registering ID codes in an IM unit 4 and an EGI unit 9, the first ID code is temporarily stored in an RAM 6 until completing registration of the ID codes of first and second keys in an EEPROM 5. Until an IG switch is switched on by a third key after registering the ID code of the second key and switching off the IG switch 15, an indicator 16 is blinked continuously twice so as to confirm registration of two different ID codes. Continuous registration of the same key can thereby be prevented, and since the blinking frequency of the indicator is not increased even in case of registering in duplicate, duplication is recognized.

IPC: H04B3/10
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To reduce an operated variable by estimating a tap coefficient while using a tap gain coefficient provided by using the training sequence of a present slot and a tap gain coefficient provided by the training of an adjacent slot. SOLUTION: At a present slot (#n), training is performed while using the training sequence of this slot. Next, at a following adjacent slot [#(n+1)], training is performed by using its training sequence. Then, the tap gain coefficient at the data part of #n is estimated by performing interpolating processing while using the tap gain coefficients estimated by the training sequences of these #n and #(n+1). In this case, as the training sequence, a synchronizing word to be used for frame synchronism between a base station and a mobile station is used, for example. When the synchronizing word is used, the frame synchronization and the training can be performed through the same sequence. Thus, by estimating the tap coefficient, the operated variable in equalizing processing can be reduced.

Abstract: PURPOSE: To enhance the reliability of transponder identification by providing an interrogator with a circuit or the like through which a transponder clock signal is taken out from the responsive signal of the transponder. CONSTITUTION: While responding to the question signal from an interrogator, the amplifier 10 of the synchronous circuit of the interrogator amplifies the responsive signal received from a transponder.
