Abstract: A partial correlation matched filter for TxID(Transmitter Identification) using an interference cancelled spreading code and a filtering method thereof are provided to deduce correlation characteristics within a short time by minimizing chip correlation operations of a correlation calculation part of a ZCD(Zero Correlation Duration) code having a long period used for watermarking in a receiving terminal, and reduce hardware volume and power consumption. A first shift register(22) shifts a transmitted spreading code. A ZCD code controller(21) outputs a switch signal in order to remove zero components among the spreading codes outputted from the first shift register. A component removing unit removes the zero components from the output of the first shift register through the switch signal of the ZCD code controller. A partial correlator(23) calculates a correlation value with a reference code after receiving the spreading code where the zero components are removed by the zero component removing unit.

CONSTITUTION: A space-time array receiving system having a finger(430) consists of a digital beam forming network(400), a demodulator(430), a rake combiner(430-D), a hard limiter(440-B), and a reference signal generator(440-A). The digital beam forming network(400) is composed of multipliers(400-A) and an adder(400-B). The demodulator(430) demodulates the output signal of the digital beam forming network(400). The rake combiner(430-D) receives the output signal of the demodulator(430) and combines symbols. The hard limiter(440-B) executes hard decision for the signal passing through the rake combiner(430-D). The reference signal generator(440-A) receives the information fed back from the finger in the demodulator(430) and the output of the hard limiter(440-B) and creates a reference signal. The finger in the demodulator(430) comprises a Doppler frequency estimator(430-F) and a correlation length selector(430-E). The Doppler frequency estimator(430-F) receives the fading channel information of a pilot channel I/Q correlator(430-A) and estimates a fading channel Doppler frequency. The correlation length selector(430-E) receives the estimated fading channel Doppler frequency and estimates the correlation length of the pilot channel I/Q correlator(430-A).

Abstract: PURPOSE: A space-time array receiving system in a CDMA(Code Division Multiple Access) and a method thereof are provided to easily cancel signals of several users located at the same region in a CDMA system under a multi path channel environment, thereby enhancing amount of a reverse direction channel. CONSTITUTION: A signal processing unit(20) consists of a multi-channel array receiver(21) which changes a plurality of signals received from an array antenna(10) into a base band digital signal. An arrival angle and beam coefficient estimator(23) estimates an arrival angle and beam formation coefficient of the received signal on the basis of a signal outputted from the multi-channel array receiver(21). A digital beam formation device(22) forms an optimum directional beam by multiplying a signal outputted from the multi-channel array receiver(21) by an estimated beam formation coefficient. A rake receiver(24) combines a signal outputted from the digital beam formation device(22) with the maximum ratio in order to maximize a signal power to noise of a user's signal to noise power. An adaptation plural user detector(25) cancels an identical channel interference signal to a signal outputted from the rake receiver(24). A controller(26) discriminates whether a user are positioned at the same position on the basis of an arrival angle of an estimated user, then controls the adaptation plural user detector(26) according to the result and performs a plural user detection method on the users positioned at the same position.

Abstract: PURPOSE: An adaptive code bank managing method for allocating code channels in a mobile communication system and an apparatus therefor are provided to calculate the maximum number of allocable code channels according to wireless channel environments, and to adaptively vary the code bank by the size of communication traffic, so as to improve efficiency in communication channel use. CONSTITUTION: If a request for using code channels is generated, a channel number adjustor of a code bank management unit calculates the number of necessary code channels(S100,S110). The channel number adjustor calculates a link gain between a mobile station and a base station, on the basis of power amount allocated to all currently used code channels, total noise and interference amount, and SIR(Signal-to-Interference Rate)(S120,S130). The channel number adjustor calculates the number of additionally allocable code channels(S140). The channel number adjustor calculates the size of a code bank(S150). A channel allocator compares the number of necessary codes with the number of available channel codes(S160). If the number of necessary codes is larger, the channel allocator declares the failure of code channel allocation(S170). And if the number of necessary codes is smaller, the channel allocator allocates code channels(S180).
