摘要
文章通过对MIMO系统、OFDM系统以及V-BLAST编码方式进行分析,论证了天线选择算法在V-BLAST编码条件下MIMO-OFDM系统的可行性。与传统的MIMO系统相比,MIMO-OFDM系统误码率更低、载波与天线间相关性更复杂。仿真证明,基于容量的天线选择算法,在MIMO-OFDM仍具有较好的实用性。
This paper analyses the feature of the MIMO and OFDM system as well as the V-BLAST coding, and demon- strates the feasibility of the antenna selection algorithm in the MIMO-OFDM system which is based on V-BLAST coding. Compared with the conventional MIMO system, the MIMO-OFDM system＇s bit error rate is lower, and the correlation between the carrier and the antenna is much more complicated. Simulation results show that the antenna selection algorithm which is based on capacity in MIMO-OFDM system still has good practicality.
