Abstract: PURPOSE: A method for controlling a traffic in a mobile communication system and an apparatus for the same are provided to control a traffic in a mobile communication system, providing a high speed packet data service on the basis of determining frame quality from the results, estimating not a CRC(Cyclic Redundancy Check) but a received SIR, in a control hold state. CONSTITUTION: A signal received through an antenna undergoes a downconverting processing by a receiving unit(100), so that the inputted signal is converted into a CDMA signal. An A/D converter(110) converts a CDMA signal of intermediate frequency to a digital signal. A PN correlator(120) takes a correlation for the digital signal by using a PN code provided from a PN code generator and provides an output signal to a traffic channel correlator(130) and a pilot filter(140). The traffic channel correlator(130) takes a correlation for a code symbol received through a traffic channel by using a Walsh code. A power control bit extractor(150) extracts a PCB(Power Control Bit) from each receiving frame of the traffic channel of which initial offset has been adjusted by the correlation of the traffic channel correlator(130). The PCB extractor(150) extracts a PCB for each frame transmitted to each PCG(Power Control Group) interval and provides it to an SIR predictor(170). A coherent detector(160) detects a receiving frame to be decoded from the output of the traffic channel correlator(130) and the output of the pilot filter(140). The receiving SIR obtained by the SIR predictor(170) is inputted to a comparator(190), and the comparator(190) compares the received SIR with a reference SIR and outputs the comparison result, which is a frame quality indicator generated for a traffic control and used for an outer loop power control, a slow power control and a channel state monitoring.

Thereby, the counterflow of fluid is intercepted and the fluid flows unidirectionally. In addition, strength is uniformly distributed so that uneven wear is prevented and certain vertical and horizontal action is performed for the stable action of products.

Abstract: PURPOSE: A circuit for ensuring a protection/unprotection margin in a flash memory is provided to prevent a data loss by applying different voltage to each word line in the time of a normal verification, an unprotection verification, and protection verification. CONSTITUTION: When a verification signal(Verify) of a high level is inputted, a PMOS transistor(P1) is turned on. And, when a normal verification signal(Normal Verify) of a high level is inputted, an NMOS transistor(N5) is turned on. For this reason, NMOS transistors(N1,N2,N3) drop the voltage of a node(A). At this time, because the protection verification signal(Protection Verify) is a low level in the time of the normal verification, a PMOS transistor(P2) is turned on, and the voltage of the node(A) is applied to a driver circuit part(40). When an unprotection verification signal(Unprotection Verify) of a high level is inputted, an NMOS transistors(N4,N5) are turned on. After this, when the verification signal(Verify) of a high level is inputted, the PMOS transistor(P1) is turned on, and the voltage of the node(A) is dropped by the NMOS transistors(N1,N2,N3). At this time, because the NMOS transistor(N4) is turned on, the voltage of the node(A) is higher in an unprotection verification than in the normal verification. A low signal of the first switch circuit part(20) turns on a PMOS transistor(P2), and the voltage of the node(A) is applied to the drive circuit part(40). At this time, the drive circuit part(40) receiving a protection verification signal(Protection Verify) outputs a high signal turning off the PMOS transistor(P2). The second switch circuit part(30) outputs a voltage(VPPI) by the protection verification signal(Protection Verify) inputted to the drive circuit part(40).
