Abstract: PURPOSE: A time synchronous acquisition method and apparatus thereof are provided to acquire time synchronous location which is suitable for a cell identifier and to reduce the size of a terminal. CONSTITUTION: A second synchronous channel signal of a time domain corresponding to a cell identifier is generated(S210). A time synchronization position is determined by performing the correlation of the second synchronous channel signal and a received signal(S220). The cell identifier is re-detected at the determined time synchronization position(S230). The cell identifier at the time synchronous position is verified(S250).

Abstract: PURPOSE: An automatic gain control method at a digital communication system is provided to keep enhanced bit resolution by operating each antenna according to calculated each gain value. CONSTITUTION: A prevarication figure examination unit(301) examines the prevarication figure of two on the receiving data signal. The prevarication figure examination unit examines the prevarication figure of the signal itself and prevarication figure of the signal envelope. A condition inspection unit(302) presently inspects the state of the gain value of AGC by using the prevarication figure of the signal radiated from the prevarication figure examination unit and prevarication figure of the signal envelope. A gain value control unit(303) finally presently controls the gain value according to the decision result of the state of the current gain value above statement.

Abstract: PURPOSE: A derate-matching method and apparatus are provided to minimize the usage of a memory by simultaneously performing a deinterleaving process and a derate-matching process. CONSTITUTION: A dilate-matching processing unit(323) dilate-matches data using a dilate-matching parameter. A deinterleaving processer(324) calculates a deinterleaving location, which corresponds to the location of each row of the data, using a deinterleaving pattern. A data output buffer(327) stores the derate-matched data in a memory address value, which corresponds to the deinterleaving location. The data output buffer outputs the derate-matched data based on the order of memory addresses. A derate-matching parameter calculator calculates the derate-matching parameter.
