Abstract: PURPOSE: A group modulating method and a receiving apparatus using the same are provided to correct errors by referring to a block code. CONSTITUTION: A receiving apparatus groups payload data bit stream(S601). A block codeword set which is composed of codeword according to a pulse-arranging combination is generated(S602). The receiving apparatus extracts candidate code word from the block codeword set(S603). The receiving apparatus selects arbitrary codeword from a candidate codeword set(S604). The receiving apparatus extracts 2^N codeword based on the selected codeword(S605). The receiving apparatus rearranges the candidate codeword a hamming distance between adjacent codeword(S606).

Abstract: PURPOSE: A sampling apparatus and a method thereof in a wireless telecommunication system is provided to obtain as same sampling effect as the high-speed sampling, even using a low-speed sampling device by a method of inserting a delay unit for delaying with a predetermined value into a signal receiving process. CONSTITUTION: A delay unit(510) delays a received signal to a block unit. A delay route selector(520) controls the delay unit for selectively applying a plurality of delay paths to the each block. A sampler(530) implements the sampling on the block delayed by the delay unit. A signal processing unit(540) merges two or more sampling blocks sampled by the sampler. A timing tracking unit(550) tracks a received timing using the merged signal. The delay routes are generated independently for the predetermined delay values.

Abstract: PURPOSE: An automatic gain control method and a receiver thereof are provided to maintain a stable reception status in the various radio environment by regularly maintaining the gain of an impulse signal inputted with ADC. CONSTITUTION: The variable gain amplification unit amplifies the gain of an impulse signal received. A quantized value is outputted by processing a quantization about the impulse signal with an amplified gain. Statistical information is generated by using the quantized value. The gain control width is determined based on the statistical information. The amplifying gain of the variable gain amplification unit is adjusted based on the gain control width. The frequency band of the received impulse signal is transformed to the base band. The matching filtering process between the quantized value and the digital impulse signal is operated.
