초록
최근 다양한 무선통신 서비스의 수요가 증가함에 따라 송·수신기의 다양한 무선통신규격 지원이 필요하게 되었다. 이런 통신 환경을 고려하면 기존의 단일대역·단일모드를 지원하는 송·수신기를 그대로 사용하는 것은 칩의 크기가 증가하며 전력소모량이 증가할 수 있다. 이러한 문제들을 해결하기 위해 몇가지 접근방법들이 시도되고있다. 특히 재구성 가능한 송·수신기(Reconfigurable Transceiver)가 관심을 받고 있다. 이런 재구성이 가능한 송·수신기의 개발 상황에 대해 조사함으로써 다양한 무선통신 규격을 지원할 수 있는 효율적인 송·수신기 구현에 대한 방향을 살펴보고자 한다.
Abstract
Recently, a transceiver is needed that supports various wireless communication standards since the demands of diverse wireless services increase. However, the simple combination of conventional singleband, singlemode transceivers would increase the chip area and the power consumption. Therefore, various approaches have been proposed to solve these problems. Especially it becomes a hot issue to design a reconfigurable transceiver which satisfies multiband/multiservice requirement with minimum hardware resources. By reviewing the development of these reconfigurable transceivers, we could find out the direction of making efficient transceivers which can support various wireless communication standards.
