Abstract
휴대전화 등과 같은 이동국을 이용하여 무선송신을 하는데 적합하다고 고려되는 코드분할 다원접속법(CDMA)에 있어서도, 현재로써는 엄격한 직교관계를 확보하기 어려우며, 따라서 수신신호를 서로 완전히 분리 할 수 없으며, 그 결과, 다른 이동국들은 간섭원이 된다. 더욱이, 만일 사용을 위한 적용의 대역폭이 정의된다면, 그 외의 다른 대역폭은 적용될 수 없다. 멀티-캐리어 변조부는 사전에 할당된 대역 내에 다수의 캐리어를 연속적으로 배치하며, 개별 캐리어를 개별적으로 변조한다. 가산기는 멀티-캐리어 변조부에 의해 변조된 다수의 캐리어를 합성한다. 안테나는 가산기로부터의 합성출력을 송신한다Even in the code division multiple access method (CDMA), which is considered suitable for wireless transmission using a mobile station such as a cellular phone, it is difficult to secure a strict orthogonal relationship at present, and thus, the received signals cannot be completely separated from each other. Other mobile stations become sources of interference. Moreover, if the bandwidth of the application for use is defined, no other bandwidth can be applied. The multi-carrier modulator continuously places a plurality of carriers within a pre-allocated band and modulates the individual carriers individually. The adder synthesizes a plurality of carriers modulated by the multi-carrier modulator. The antenna transmits the composite output from the adder
