Abstract

In this paper, we compare and analyze the spectral efficiency of representative adaptive MIMO algorithms in indoor environments. We first briefly investigate the modulation and demodulation schemes of MIMO algorithms to be compared and then implement adaptive algorithms by using BPSK and square QAM schemes up to 256QAM. We finally compare the spectral efficiency of adaptive MIMO algorithms employing (2$\times$2) or (4$\times$4) antenna array through the computer simulation in indoor environments.

본 논문에서는 실내 환경에서 대표적인 적응 MIMO 알고리즘들의 스펙트럼 효율을 비교, 분석한다. 먼저, MIMO 알고리즘들의 변복조 기법을 간략히 고찰하고 BPSK 와 256QAM 까지의 정방형 QAM 변조방식을 이용하여 적응 알고리즘을 구성한다. 끝으로, 실내 전파환경에서 (2$\times$2) 혹은 (4$\times$4) 안테나 어레이로 구성되는 적응 MIMO 알고리즘들의 스펙트럼 효율을 시뮬레이션을 통해 비교, 분석한다.
