Abstract: PURPOSE: A sequential decoding apparatus of a mobile communication system and a method thereof are provided to efficiently decode a stream of symbols encoded by a convolution code when the stream is transmitted through a channel in the mobile communication system. CONSTITUTION: A CPU(202) controls a total decoding operation. An optimal path determination buffer(210) sequentially stores an optical path. A competitive path determination buffer(210) sequentially stores at least one competitive path. A buffer controller controls the optimal path determination buffer(210) and the competitive path determination buffer(210) using a control signal from the CPU(202). An encoder(214) encodes signals from the optimal path determination buffer(210) and the competitive path determination buffer(210) by the set bit number. A bit metric calculation(216) calculates a metric using the signals from the optimal path determination buffer(210) and the competitive path determination buffer(210) and an input signal.

Abstract: PURPOSE: A multiuser interference cancellation receiver for a TDD-CDMA(Time Division Duplex-Code Division Multiple Access) system and a method for controlling the interference cancellation are provided to perform interference cancellation for signals having high power values even when differences of signal power values are wide among users, so as to minimize errors in the detection of user signals having low signal power values. CONSTITUTION: A data extractor(100) extracts data from received signals and outputs the extracted data. A signal delay part(200) delays the signals outputted from the data extractor(100) during a predetermined time, and outputs the delayed signals. An interference cancellation selection part(300) extracts midamble signal channels from received original signals, to select and output users of the subject of the first interference cancellation. The first step interference cancellation block(400) receives data of the received signals from the data extractor(100), to perform the first parallel interference cancellation for the selected users of the first interference cancellation subject and output reproduction signals. And the second step interference cancellation block(500) receives data of the received signals delayed during the predetermined time and outputted from the signal delay part(200), to perform the second parallel interference cancellation using the first reproduction signals outputted from the first step interference cancellation block(400).

Abstract: PURPOSE: A device for estimating a channel in a time division bidirectional communication system is provided to use a channel estimating method from a chip unit, a symbol unit, and a time slot, thereby minimizing an error caused during channel estimation. The device is provided to use a simple averaging method, thereby reducing random FM phenomenon caused by a channel estimating error. CONSTITUTION: A converter(100) receives a transmitted RF signal, and converts the signal into a baseband signal. A matching filter(200) filters the converted signal. A multiplier(300) multiples a signal sampled by a sampling period with chip units from the filtered signal by a midamble sequence for I and Q codes. An adder(400) adds signals as many as all midamble chips from the multiplied signal. An accumulator(500) divides the added signals as many as the number of the midamble chips, and obtains an average value. A channel estimating calculator(600) calculates a channel estimating value through consecutive two time slots or one-time slot from output values of the accumulator(500).

Abstract: PURPOSE: A method for restoring a resource object in a distributed object system is provided to automatically restore a resource object by using a transaction log, which refers the resource object and stores an object identifier. CONSTITUTION: A restart module of a transaction server is started(200). A log record stored in a log file is read(202). It is judged whether the sort of the log record is an approved record(204). In case that the sort is the approved record, next log record is read(206). It is judged whether the log record read is an end of the log file(208). In case that the log record isn't an end of the log file, it is judged whether object identifiers of the log records are corresponded(210). In case that the log record is the end of the log file, it is judged whether the number of resources of a restorable server is "0"(212). In case that the number is "0", the number of resource is reduced as much as "1". Therefore, a resource object is restored(214).
