본 논문에서는 정확한 전파 모델링과 빠른 전파 예측에 필요한 다중 경로 현상을 효과적으로 포착하는 매우 효율적인 데이터 구조를 도입하는 데 중점을 둡니다. 우리는 고속 광선 추적에서 기존 벡터 표현(VR) 형식을 개선하기 위해 건물과 같은 마이크로파 마스킹 객체의 원형 표현(CR)이라는 새로운 객체 표현 절차를 제안합니다. 제안된 CR은 중심점과 반경으로 표시되는 원으로 건물을 캡슐화합니다. 이 구성에서 CR은 본질적으로 더 높은 기하학적 구조를 위한 기본 구성 요소 역할을 하여 VR을 단독으로 사용할 때보다 효율성을 더 향상시킵니다. 하나의 건물을 표현하려면 하나의 CR만 필요하지만 VR에서는 여러 개의 벽 벡터가 필요합니다. 결과적으로, 제안된 방법을 사용하면 광선 추적에서 계산량이 크게 감소할 수 있습니다. 우리의 목표는 효과적인 전파 예측 모델링을 위해 데이터 구조화의 효율성을 달성하기 위한 솔루션으로 CR을 보여주는 것입니다. 제안된 방법에 의해 계산 부하가 감소함을 보여준다. 광선 추적을 통해 결정론적 전파 모델에서 CR의 계층적 구조를 사용하면 추가 감소가 달성 가능한 것으로 나타났습니다. 시뮬레이션 결과, 제안된 CR 방식은 잠재적인 산란 물체의 수에 비례하여 계산 부하를 감소시키며, 계층적 구조는 계층적 팔진트리 구조에서 약 50%의 계산 부하 감소를 달성함을 나타낸다.

Abstract: This paper focuses on introducing a highly efficient data structure that effectively captures the multipath phenomenon needed for accurate propagation modeling and fast propagation prediction. We propose a new object representation procedure called circular representation (CR) of microwave masking objects such as buildings, to improve over the conventional vector representation (VR) form in fast ray tracing. The proposed CR encapsulates a building with a circle represented by a center point and radius. In this configuration, the CR essentially functions as the basic building block for higher geometric structures, enhancing the efficiency more than when VR is used alone. Only one CR is needed to represent one building while several wall vectors are required in VR. As a result, a significant computational reduction can be achieved in ray tracing by the proposed method. Our aim is to show CR as a solution to achieving efficiency in data structuring for effective propagation prediction modeling. We show that the computational load is reduced by the proposed method. Further reduction is shown attainable using the hierarchical structure of CR in a deterministic propagation model, undergoing ray tracing. The simulation results indicate that the proposed CR scheme reduces the computational load proportionally to the number of potential scattering objects while its hierarchical structure achieves about 50% of computational load reduction in the hierarchical octree structure.
