摘要:
MIMO-OFDM系统能够极大地提高无线通信系统的容量和频谱利用率,为了增加系统的可靠性,采用空时分组编码来获得空间分集.针对采用多天线所带来的射频链路增加,利用天线选择技术使系统不完全受射频成本的限制.该文提出了一种基于基本的MIMO-OFDM系统结构的改进天线选择方法,并将STBC应用到此改进方法的系统中.仿真结果表明,在频率选择性衰落信道中,该方法在通过天线选择提高了天线利用率的前提下,降低了系统的误码率,获得了分集增益.
Abstract:
Multiple input multiple output-orthogonal frequency division multiplexing(MIMO-OFDM) systems can greatly improve the capacity and frequency spectrum utilization of wireless communication. In order to increase reliability, STBC can be used to obtain the degree of spatial diversity. For the increase of RF link by using multi-antenna,antenna selection techniques can be used to eliminate the limit of RF cost to system. Based on the traditional MIMO-OFDM system, this paper proposed an improved antenna selection method, and applied space-time block code to this improved method system. The simulation results shows that, in frequency selective fading channel, the method can decrease the system’s bit error rate and obtain diversity gain under the premise of improving antenna utilization by antenna selection techniques.
