MIMO 시스템에서 16-QAM의 Semi-Definite Relaxation에 기반을 둔 선형 검출 기법

Abstract

This paper suggests the detecting method in which it uses the candidate symbol obtained through PI-SDR, the little computational complexity is required. By using the candidate symbol matrices obtained through PI-SDR, ZF and MMSE method was applied and the received signal was detected. The linear detecting method using PI-SDR candidate symbol is out of the performance than ML detecting method but the complexity is low. Because of using the symbol come close to the solution of ML, the proposed method`s performance is better than the existing ZF and MMSE method.
