Abstract

Bit error rate(BER) performance of each bit for hierarchical M-ary phase shift keying(H-MPSK) modulation scheme is changed according to the phase parameters. Thus, a method to find the phase parameters appropriate to the requests of the system is needed. In this paper, we propose a method to obtain the phase parameters from an approximate approach of BER for H-MPSK and verify a validity of the proposed method through the previously provided expression for analyzing an exact error probability of H-MPSK.

계층적 M진 위상 편이 변조(hierarchical M-ary phase shift keying) 방식은 설정된 위상 파라미터에 따라 각 비트의 오류 성능이 변하기 때문에 각 시스템의 요구에 맞은 위상 파라미터 값을 구할 수 있는 방법을 필요로 한다. 따라서 본 논문에서는 계층적 M-PSK 변조 방식에 대한 BER의 근사적 접근을 통해 원하는 각 비트의 오류 성능에 따라 중요 위상 파라미터를 찾을 수 있는 방법을 제안하고, 이전에 제시된 계층적 M-PSK 변조 방식에 대한 정확한 오류 성능 분석 방법을 통하여 제안한 방법의 정당성을 검증한다.
