Abstract: PURPOSE: An apparatus for controlling a transmission antenna diversity in a mobile communication system is provided to apply variable weights to each of antennas used in the transmission antenna diversity, according to channel states, and to perform an adaptive weight calculation for calculating a present weight by using a previous weight. CONSTITUTION: Channel estimation blocks(1004,1006) input a channel-despreaded primary common pilot channel and a secondary common pilot channel, and estimate channel states of down channels. A weight calculator(1021) has a symbol table having a differential weight relating to a predetermined index, and has a previous normalization weight vector. The weight calculator(1021) finds an index of a differential weight vector in which the size of a receiving signal becomes maximum, by using channel state information estimated within a regular period, the normalization weight vector, and the differential weight vector of the symbol table. The weight calculator(1021) transmits the found index to a base station, and calculates a normalization weight vector by the differential weight vector and a predetermined value, then updates the previous normalization weight vector. The weight calculator(1021) calculates a fixed weight vector at regular intervals, and initializes the normalization weight vector.

Abstract: PURPOSE: A communication running method of an air conditioner is provided to improve ability corresponding to power noise by stopping scanning the next address and starting to scan a random address twice more if error on a modem communication line occurs during scanning a random address once. CONSTITUTION: Plural relays of each indoor unit set addresses of each indoor unit with a deep switch. A CPU receives the set addresses of the indoor units and memorizes each address. When an air conditioner is powered on, the CPU initializes the entire system of the air conditioner and sets 1 at a random address to scan each address from 1 to 16 sequentially. Scanning for deciding mounting of each indoor unit is performed once per second through a modem communication line. In occurrence of communication error, the CPU decides whether a random address is scanned three times to check if the error is temporary on the modem communication line caused by power noise. If so, the CPU processes an indoor unit of the random address as communication error by recognizing that the indoor unit is not set. If the random address is larger than 16, the CPU decides that all of the indoor units from 1 to 16 are scanned sequentially. Therefore, the scanning is performed all over again.
