A method of efficiently collecting a charge for the payment of money for an article of merchandise that are purchased is used in a charge collection system having a contactless storage medium in an article tag which has recorded product information therein, a contactless storage medium in a customer terminal which has recorded customer ID information therein, and a charging device in a store. The method comprises the steps of reading the product information from the contactless storage medium in the article tag into the charging device (step 71), calculating a total amount of money with the charging device based on the read product information (step 72), settling the payment of the calculated total amount of money with the charging device by receiving corresponding cash or reading the customer ID information from the contactless storage medium in the customer terminal (steps 74-78), and recording information of the settled payment in the contactless storage medium in the article tag (steps 79, 80).

Cells are searched at a high speed using an initial synchronization method and a receiver for a DS-CDMA inter base station asynchronous cellular system. A base band received signal is input to a matched filter and is correlated with a spread code supplied from a spread code generator. A signal electric power calculator calculates the electric power of the correlation output of the matched filter, and outputs the result to a long code synchronization timing determiner, a threshold value calculator, and a long code identifier. During the initial cell search, the spread code generator outputs a short code #0 that is common to the control channel of each of the base stations. After the long code synchronization timing has been determined, each of the segments of the N chips which constitutes a portion of the synthesized spread code sequence synthesized from a long code #i that is unique to each of the base stations and the short code #0 is sequentially replaced and output.

A signal characterizer for performing functional transformations such as Fast Fourier Transforms (FFTs), which converts an input serial analog signal into a plurality of parallel discrete signals using an analog-type serial-to-parallel converter. The discrete signals are then supplied to the input terminals of butterfly operation circuits to process the parallel discrete signals into a plurality of transformed signals. A switch supplies the transformed signals to a serial signal output terminal. The switch is controlled by a controller so that the input signal sequence is converted to a serial signal sequence according to a predetermined order.

The present invention provides a matched filter which can refresh an entire while keeping the speed of a calculation comparable to a small sized circuit. The first and second addition circuits of a matched filter of the present invention are classified into a plurality of groups, the first and second auxiliary adders replace functions for the groups of the first and second adders respectively. The outputs of the first and second adders are then inputted to the first and second subtractors, respectively, and the refreshing means appropriately refreshes the groups replaced by the first and second auxiliary adders. Further, the present invention decreases the number of auxiliary sapling and holding circuits to be used, and decides the refreshing intervals by considering the change of the voltage caused by leakage and other permissible errors of output voltage.
