Abstract: PURPOSE: An interference avoiding method in a wireless communications system and a device thereof are provided to avoid interference by detecting downlink interference. CONSTITUTION: A received signal measuring part (340) measures received signal intensity of a first uplink symbol. An interference avoiding part (330) calculates the ratio between the measured received signal intensity and reference noise interference. The interference avoiding part determines the status of interference from the downlink of a remote base station by using the calculated ratio. If interference from the downlink of the remote base station is determined to exist, the interference avoiding part erases the first uplink symbol. [Reference numerals] (300) RF receiving part; (310) FFT unit; (320) Noise interference estimating part; (330) Interference avoiding part; (340) Received signal measuring part

Abstract: PURPOSE: An apparatus for decoding in a communication system and a method thereof are provided to perform decryption with a little amount of memory by repetitively performing a trace back in the last window. CONSTITUTION: Path metrics in each state are determined a trellis. An initial state of a trace back is selected in the last window. The trace back is repetitively performed within the final window range more than twice. The repetition of the trace back is completed. Decrypted bits are determined using a survived path of the final trace back. The initial state belongs to a state having a maximum path metric. The initial state belongs to a '0' state. The information for the trace back about states belonging to one or more windows excluding the last window is discarded.

Abstract: PURPOSE: An iterative decoding method and an iterative decoding apparatus are provided to improve a bit error rate by outputting estimated values of all corresponding variable nodes as a final decoding result when a minimum number of check nodes dose not satisfy a parity check formula. CONSTITUTION: An iterative decoding method and an iterative decoding apparatus include a data buffer and a decoding block. The first estimated values corresponding to all variable nodes are stored into a buffer when an error bit number is minimum by using an iterative decoding algorithm while increasing the number of iterative decoding from one to a maximum iteration number gradually(S10-S30). The first estimated values stored in the buffer are outputted as a final decoding result when the iteration number is reached to the maximum iteration number(S40-S50).

Abstract: PURPOSE: A hierarchical decoding apparatus is provided to reduce a whole bit error rate by applying one of various decoding algorithms based on a decoding result of a received signal. CONSTITUTION: In a hierarchical decoding apparatus, a buffer(2) buffers a reception signal transmitted through a channel according to a control signal of a controller(8). A first selector(3) transmits an output signal of the buffer to one among lots of decoder stages(4,5,6) in response a first selection signal. A decoder stages perform decoding of the reception signal according to a decoding algorithm having different computational complexity. A second selector(7) transmits a decoded signal from one decoder stage to the controller in response to a second selective signal. The controller analyzes a decoded signal of the second selector and determines whether decoding of the reception signal is fail or not based on an analyzed result.
