V-BLAST MIMO-OFDM 시스템에서 신호 검출 알고리즘

Abstract

In this thesis, the MIMO-OFDM system with Vertical Bell laboratories layered space-time (V-BLAST) structure is analyzed. And the typical detection algorithms are introduced. For improving the signal detection algorithm, we proposed an improved QRD-M detection using channel matrix ordering, OSIC and varying value of survivor point. The simulation result shows that the proposed algorithm obtains a better tradeoff between complexity and performance.
