摘要： The problems of a transmitter/receiver of direct-conversion structure are solved by providing a multiband OFDM_UWB transmitter/receiver of a low-IF structure. A low-IF receiver has a structure not needing frequency conversion by a second local signal by re-arrangement such that the subcarrier is rotated after FFT and the same AD conversion clock as a direct-conversion receiver is used. For the preamble part not subjected to FFT, a sequence produced by multiplying the original preamble pattern by the IF frequency is used to enable preamble detection.

摘要： 멀티밴드 OFDM_UWB 송수신기(送受信機)를 Low-IF 구성으로 하고, 다이렉트?컨버젼 구성의 송수신기에서의 문제점을 해결한다.
Low-IF 수신기에서, FFT 후(後)에 서브캐리어를 회전시키는 재배열(竝替; re-arrangement)을 행함으로써, 제2 로컬 신호에 의한 주파수 변환(周波數變換; frequency conversion)을 불필요(不要; not needing)하게 함과 동시에, 다이렉트?컨버젼 수신기와 같(同)은 AD 변환 클럭을 이용한다. 한편, FFT를 가하지 않는 프리앰블(preamble) 부분에 대해서는, 원래(元; original)의 프리앰블?패턴에 미리 IF 주파수를 승산(乘算; multiplying)해서 얻은 시퀀스를 이용함으로써, 프리앰블 검출할 수 있도록 한다.
