Performance and Implementation of a Space-Time Coded MIMO OFDM System Using Frequency Spread Coding
一种结合频率扩展编码的空时码MIMO OFDM系统性能及实现

In this paper, a space-time coded MIMO (Multiple-Input Multiple-Output) OFDM (Orthogonal Frequency Diversion Multiplexing) system using frequency spread coding is proposed based on the fact that the fading effects of the transmitted signals on each sub-carrier are different owing to the frequency-selective fading property. The simulation results indicate that the proposed scheme not only effectively exploits the inherent frequency diversity of the frequency-selective channel and maintains the spectrum efficiency of system, but also has a low complexity and is easy to realize compared to other MIMO OFDM systems.
