Abstract: A synchronous detector used in a code division multiple access (CDMA) communication receiver comprises a correlator and a pre-synchronous decision circuit. The correlator calculates a plurality of correlation values between a received signal spread with an x-chip sequence of a spread code and n-chip correlation coefficients for different phase timings. The pre-synchronous decision circuit, coupled to the correlator, generates at least one timing control signal indicating a phase timing corresponding to a highest correlation value. The correlator comprises a synchronous estimator that estimates a synchronous phase by calculating the correlation values between the received signal and the n-chip correlation coefficients every cycle of the spread code and by accumulating the correlation values. The synchronous estimator comprises an n-chip correlation coefficient generator that generates the n-chip correlation coefficients at phase timings indicated by a timing control signal.

Abstract: The present invention provides a method of processing data transactions in a banking terminal which permits appropriate cash handling of received money and disbursement of money due as change even in the case when data which is indicative of the types of denomination of the received money is inputted after data indicative of an actual or overall amount of a transaction is inputted, and also even when data which is indicative of the types and denominations of the received money or sorts of money is inputted before data indicating an actual amount of the transaction involved is inputted.

Abstract: A printer control system including a printer and a control unit for controlling the printer is disclosed. The printer function designating information which is used to designate the functions, which vary in accordance with the kind of a job to be done, of the printer is stored in a memory in the control unit. When a printing operation of the printer is started, the function designating information is outputted from the memory, transmitted from the control unit to the printer and stored temporarily in a memory provided in the printer. Various kinds of operations are carried out in accordance with a control code transmitted from the control unit to the printer, and an operation for a designated job is carried out with reference to the function designating information.
