Abstract

Technologies to utilize the limited frequency resource more efficiently in spatial and temporal are accelerated. In this paper cognitive algorithms as brain of cognitive radio, kind and characteristics of databases which are necessary parts for algorithm were reviewed and summarized. And an example of cognitive engine on which database and algorithm are executed was described also. Because the current status of development of technologies relating to cognitive radio is at the initial stage, the best database, algorithm and engine for a cognitive radio were not suggested, but the direction of development and factors to be considered during development of relating technologies were explained.

한정된 자원인 주파수 자원을 보다 효율적으로 사용하고자 시간적/공간적으로 주파수를 공유하는 기술 개발이 가속화되고 있다. 본 논문에서는 대표적인 주파수 공유 기술 중 하나인 Cognitive Radio에서 두뇌 역할을 하는 인지 알고리즘과 필요한 데이터베이스 종류 및 특성을 알아보고, 이들이 이용되는 Cognitive Engine을 구현한 예를 보였다. Cognitive Radio 관련 기술은 아직 연구 초기 단계이기 때문에 Cognitive Radio에 최적인 데이터베이스, 알고리즘, 엔진을 제시 하지는 못했지만 관련 기술 개발 방향을 제시하고 개발 시 고려사항들에 대해 설명하였다.
