Abstract
Triangular 신호점 배치를 갖는 Triangular QAM이 직교 신호점을 갖는 Square QAM에 비해 좋은 SER 이득이 있다고 알려져 있다. 본 논문에서는 지금까지 연구되어 오고 있는 TQAM에 대한 심벌 오류 성능을 closed-form 형태로 유도한다. 시뮬레이션을 통해 일반화된 TQAM의 유도 수식을 검증한다. 그리고, 주어진 SNR에서 일반화된 TQAM에 대한 최적의 신호점 배치 방안이 제시한다.
It is known that triangular QAM with triangular signal constellations gets better SER gain than square QAM with rectangular signal constellations. In the paper, we propose an exact and general closed-form expression of the probability of symbol error for generalized TQAM, which has been currently researched. We verify that the simulation is consistent with the derived equation of generalized TQAM. And, we also suggest the optimal signal constellation schemes for generalized TQAM at given SNR values.
