The Study of STBC-MIMO-OFDM System Performance Based on ZF Pre-coded
Shuili Zhang · Mechanical Management and Development · 2010
The focus on MIMO-OFDM communication system is researched.Space-time block codes (STBC),as the core of MIMO technology,can improve system capacity and spectral efficiency.Based on zero-forcing linear pre-coding technique,the signal sents to zero-forcing linear equalization code before STBC.For 2 × 2 or 3 × 2 of the STBC-MIMO-OFDM communication system,it may reduce the bit error rate and increase system performance.
