Abstract: PURPOSE:To suppress the increase of the hardware quantity against the diagnosis of a collation circuit by giving the retrieval or collation data to a 1st or 2nd input of an idle one of collation circuits as the diagnostic data and performing the diagnosis according to the result of collation. CONSTITUTION:The common retrieval data are given previously to the collation circuits 3a-3n via a common bus 7. Then the collation data (F data) stored in a memory 1 are transferred successively to the circuits 3a-3n for each block. The normal collation is carried out when the F data are transferred to all circuits 3a-3n. When one of these circuits 3a-3n becomes idle, the transferred F data stored in the memory 1 are sent to the 1st and 2nd inputs of the idle collation circuit for execution of the diagnosing/collating operations. Then the information showing that the normal or diagnostic collation is carried out at each of circuits 3a-3n and the information on the collation result are outputted to a deciding circuit 4 via a signal line 10. Thus it is not required to add any diagnostic check circuit into each collation circuit nor to duplicate these collation circuits.

Title: Mobile communication terminal
Inventor: ICHIHARA MASAKI
IPC: H04W48/16
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a method for performing initial adjustment of a reference oscillator of a terminal of a mobile communication system in which the automatic correction of a frequency becomes possible only when received signals are normally demodulated as in the case of the CDMA(code division multiplex) system. SOLUTION: At the beginning of power supply, a switch 10 is set in an initializing mode. A reference oscillator control circuit 5 is initialized and, in this state, the frequency of a reference oscillator 6 is usually shifted largely. When base station searching is first performed in any case and no base station is caught, a frequency offset generating circuit 12 generates an offset signal and the frequency of the oscillator 6 is shifted through the control circuit 5. By repeating the shifting of the frequency of the oscillator 6 in such a way, the base station searching is continuously performed until a base station is caught. When the base station is caught, the conventional frequency adjustment is performed by turning the switch 10 to an AFC side.
