DS-CDMA에서 인지 무선(CR)에 대한 주파수 대역 감지의 새로운 방식인 무작위 행렬 이론(RMT)의 중요한 분기가 된 자유 확률 이론(FPT)을 기반으로 합니다. ) 다중 사용자 네트워크가 제안됩니다. 해당 분야의 이전 연구와 달리 새로운 방식은 사용자의 확산 순서에 대한 지식이 필요하지 않으며 무작위 행렬의 점근적 자유 동작의 동작과 관련됩니다. 시뮬레이션 결과는 점근적 주장이 전통적인 에너지 검출 방식과 랜덤 매트릭스 이론에 기반한 다른 방식을 능가하는 소수의 관측값(시간에 따라 변하는 토폴로지에 편리함)에 대해서도 유효하다는 것을 보여줍니다.

Abstract: Based on Free Probability Theory (FPT), which has become an important branch of Random Matrix Theory (RMT), a new scheme of frequency band sensing for Cognitive Radio (CR) in Direct-Sequence Code-Division Multiple-Access (DS-CDMA) multiuser network is proposed. Unlike previous studies in the field, the new scheme does not require the knowledge of the spreading sequences of users and is related to the behavior of the asymptotic free behavior of random matrices. Simulation results show that the asymptotic claims hold true even for a small number of observations (which makes it convenient for time-varying topologies) outperforming classical energy detection scheme and another scheme based on random matrix theory.
