Abstract: A device for generating a clock jitter and a testing device including the same are provided to reduce manufacturing cost and complexity by generating a clock signal including a jitter. A waveform generator(110) reproduces a predetermined waveform. The waveform generator generates an arbitrary waveform by converting various waveforms. The waveform generator sets amplitude and frequency of an output waveform. A power source circuit part(120) outputs a DC power source. The power source signal outputted from the power source circuit part is added to an output waveform of the waveform generator. The added result is inputted to a PLL(Phase Locked Loop) circuit part(130) as a power source. The PLL circuit part makes frequency of an inputted reference signal(170) and oscillation signal(180) identical. The PLL circuit part includes a phase comparator(140), a loop filter(150), and a voltage-controlled crystal oscillator(160).

Abstract: An apparatus and a method for modulo N operation are provided to perform efficiently a modulo 3 for an arbitrary integer N by adding a logical circuit in accordance with twice AND operations for outputting a modulo operation result more rapidly. A method for modulo N operation includes the following several steps. An apparatus for modulo N operation checks whether a specifically inputted integer value N is for an M1 bit operation and performs an AND operation for lower M1 bits and a binary number of 0101(S200,S202). The apparatus determines an AND operation result and changes output register values according to the result(S204). If the result is a binary number of 0101, the apparatus adds 2 to an output register(S206), if 0, adds 0 to the output register(S216) and if neither 0101 nor 0, adds 1 to the output register(S218). Then, the apparatus performs an AND operation for the lower 4 bits and a binary number of 1010(S208), determines an AND operation result(S210), and changes the output register values according to the result. If the result is a binary number of 1010, the apparatus adds 4 to the output register(S212), if 0, adds 0 to the output register, and if neither 1010 nor 0, adds 2 to the output register(S222). Then, the apparatus performs a 4 bit shift right for the inputted integer N(S214). Then, the apparatus abandons corresponding bits, and repeats the steps of S202 to S222. In case of a 4*M bit operation, the apparatus performs the shift right M times(S226), and checks whether the result value is lower and equal to 3(S228). The apparatus repeats the steps of S228 to S248 until the result value is 3.

Abstract: An apparatus and a method for synchronizing a system of a base station modem based on a DSP(Digital Signal Processor) are provided to facilitate time synchronization of the system between base stations by performing synchronization and controlling a point of time of a transmitting signal by measuring a difference value between reference clocks for synchronization and the DSP. An apparatus for synchronizing a system of a base station modem based on a DSP comprises a DSP chip(200) and an external device(202). The DSP chip is mounted on the base station modem. When a control signal for synchronizing the system is received in the DSP chip, predetermined numbers of digital transmitting signal samples are made and transmitted, and a point of transmitting time is adjusted according to a control signal for adjusting the point of transmitting time of the transmitting signal. The external device transmits the control signal for synchronizing the system to the DSP chip and receives the digital transmitting signal samples. The signal sample is compared with a synchronization clock signal received from a base station controller, and a time distance between two signals is calculated. The external device transmits the control signal for adjusting the point of transmitting time of the transmitting signal of the DSP chip for matching the time distance between two signals so as to match a reference point of transmitting time of the transmitting signal of the DSP chip and a point of time of the synchronization clock signal.

Abstract: An apparatus and a method for generating an OVSF(Orthogonal Variable Spreading Factor) code are provided to efficiently generate an OVSF code by dividing a small memory into several tables. A memory unit(100) stores an OVSF code including plural tables divided according to storage capacity. An OVSF code generating unit(200) generates the OVSF code, and divides it by size for which limited storage capacity of the memory unit(100) is considered, and tables the divided codes to store them in the memory unit(100). An OVSF code detecting unit(300) selects a table in which the OVSF code to be detected is stored and searches a storage address, and detects the OVSF code stored in the memory unit(100) corresponding to the searched storage address.

Abstract: PURPOSE: A method for controlling soft handoff of a mobile station in a mobile communication system is provided to minimize soft handoff of excessively occupying wireless resources, in order to effectively use the wireless resources as minimizing call cut-off during the soft handoff, thereby increasing capacity of the wireless resources. CONSTITUTION: A mobile station performs an initialization operation(401). The mobile station decides whether currently registered active sets are more than two(402). If so, the mobile station checks whether an energy value of an active set having maximum energy strength is higher than a 'T_EXCELLENT' value(403). If so, the mobile station analyzes whether a flag variable value is '0'(404). If so, the mobile station sets a flag to '1', backs up a current 'T-TDROP' value in a memory, sets a 'T_TDROP' value to be used to '0', backs up a current 'T_ADD' value in the memory, and replaces the 'T_ADD' value with a 'T_ADD_HIGHER' value(405). If the flag variable value is not '0', the mobile station maintains a speech channel state(408).

Abstract: PURPOSE: A method for transmitting upward data at a media access control layer of an asynchronous mobile communication terminal is provided to simplify a data transmission process among a PHY layer, an MAC layer, and an RLC layer. CONSTITUTION: An MAC(Media Access Channel) layer receives a MAC setup request primitive(CMAC-CONFIG-REQ) from an RRC(Radio Resource Control) layer(500). The size of data transmittable to a radio bearer corresponding to a set DCH(Data Channel) parameter is initialized as the maximum TF(Transport Format)(501). If the MAC layer receives a transmission synchronization command primitive(TRC-SYNC-CMD) from a PHY(Physical) layer, the size of data transmittable to all radio bearers corresponding to the corresponding transmission channel is set up to transmit data to an RLC(Radio Link Control) layer through an MAC status indicator(MAC-STATUS-IND)(502-504). The MAC layer sets up the size of the TF not exceeding RLC data length as the size of data transmittable to the next TTI(Transmission Time Interval) to the radio bearer received an MAC status response primitive(MAC-STATUS-RES) from the RLC layer(506). The MAC layer returns to wait TRC-SYNC-CMD(507). To the radio bearer received MAC data request primitive(MAC-DATA-REQ) from the RLC layer, an MAC header is added to configure protocol data units and selects a TFI(Transport Format Indicator) fitting to the RLC data length to send physical data request primitive(PHY-DATA-REQ) to the PHY layer(508-510). A TF not exceeding RLC buffer size is sets as the size of the data transmittable to the next TTI(511).
