Abstract: An automatic gain control device suitable for controlling an effective bit of an uplink receiving terminal and a method thereof are provided to perform automatic gain control by using only instantaneous power values of signals received from a terminal. An ADC(Analog and Digital Converter)(200) converts signals received from terminals into digital signals. A gain controller(400) controls a gain of data outputted from a buffer and outputs the data to a receiving module(800). A power measuring unit(500) determines a gain control coefficient and transmits the coefficient to the gain controller. A path control switch(600) blocks or connects a path of data.

Abstract: An apparatus and a method for removing intersymbol interference in a mobile communication system remove intersymbol interference element between reception signals by using a frequency domain equalizer. A first equalizer(200) estimates a channel from the received signal and performs equalization for the received signal according to the estimated channel, and outputs a first signal. A signal processor(300) removes intersymbol interference element from the first signal and recovers the first signal as a transmission signal. A second equalizer(400) generates a second signal from the restored transmission signal and extracts the intersymbol interference element of the first signal from the second signal and transmits the extracted signal to the signal processor.

Abstract: An apparatus and a method for matching a base station with a terminal are provided to connect the terminal with the base station by cable when at least one of the terminal and the base station does not normally operate, thereby stably performing a connection test between the terminal and the base station. The first connector collects a signal outputted from a base station(200). The second connector collects a signal outputted from a terminal(300). A signal controller(150) converts the size of the signal collected through the first connector and provides it the second connector. The signal controller converts the size of the signal collected through the second connector and provides it the first connector. A header(140) receives matching information including at least one of frame synchronization and a frame number from the base station and transmits the matching information to the signal controller. The third connector transmits the matching information to the terminal.

Abstract: A transmission apparatus and method thereof, and a reception apparatus and method thereof in a communication system are provided to reduce a time delay caused by physical channel mapping and data interleaving. A transmission apparatus includes a data interleaver(140), and a channel mapping unit(150). The data interleaver divides data into a plurality of data blocks, and then interleaves each of the divided data blocks. The channel mapping unit maps the interleaved data blocks to a physical channel. The physical channel has a combination of a plurality of symbols within a time domain and a plurality of sub carriers within a frequency domain. The data interleaver has a data divider(142), a plurality of block interleavers(1441~144n) and data concatenating unit(146). The data divider divides the data into the data blocks. The block interleavers interleave the data blocks, respectively. The data concatenating unit concatenates the interleaved data blocks. The interleaving time of a first interleaver among the block interleavers is overlapped with the interleaving time of a second interleaver among the block interleavers.
