Abstract: PURPOSE: A method for transferring data to suppress interferences between adjacent channels is provided to recognize the state of a currently used channel, thereby preventing interference about the channel. CONSTITUTION: A free channel searching unit(800) searches an available free channel by a free channel search request. A channel state recognizing unit(810) recognizes an adjacent channel state by detecting interference between adjacent channels. The channel state recognizing unit selects a transmission channel based on a state recognition result. A transmission signal waveform determining unit(820) maps transmission data on a sub carrier according to the state of the transmission channel selected by the channel state recognizing unit. The transmission signal waveform determining unit generates an OFDM symbol using a mapping result. An OFDM baseband signal transmitting unit(830) generates an OFDM baseband signal. The OFDM baseband signal is transmitted through an RF transmitting unit(842).

Abstract: 본 발명은 고집적 고속 파이프라인 RLS(Recursive Least Squares) 추정 장치 및 방법에 대하여 개시한다. 본 발명은 RLS 알고리즘에 파이프라인(Pipeline) 특성을 부여함으로써, 고속 처리가 가능한 HIP-RLS(Highly Integrated Pipelined RLS) 추정 장치 구조를 제안한다. 본 발명에서 제안하는 HIP-RLS 추정 장치는 기존의 CORDIC(COordinate Rotation DIgital Computer)기반 RLS 구조의 추정 장치에 비해 집적도가 높으므로 칩 사이즈를 소형화할 수 있어 동일한 웨이퍼(WAFER)로 기존보다 많은 칩을 생산할 수 있다.
또한, 본 발명에 따른 HIP-RLS 추정 장치는 신호처리 속도가 빨라 무선통신을 고속화하는데 적합하다.

Abstract: A tone channel equalizer is provided to rapidly perform estimation of a receiving signal by using a tone equalizer which applies a probability slope-lattice module. A sample delay unit delays a receiving signal. A reader(203) reads a delay signal of the sample delay unit with a fixed time period. A calculation part(201) subtracts the receiving signal in a final output signal of the sample delay unit. A probability slope-lattice module(202) outputs a result value of an addition calculation by repetitively performing an operation calculating an output signal and a delay signal of the calculation part. A fast fourier transform part(204) transforms the delay signal of the reader. The calculation part outputs a signal estimating value by using an output signal of the fast fourier transform part and an output signal of the probability slope-lattice module.
