- 针对影响V-BLAST系统的天线阵列相关性的因素以及各因素综合作用下对系统性能存在重大影响这一情况,基于V-BLAST系统模型以及天线相关性理论,提出相应的影响天线相关性因素的理论模型和系统性能分析模型,并对阵列相关性及系统误码率和信道容量性能进行多因素及综合仿真。仿真得到天线间距、波束到达角、角度扩展和耦合各单个因素和综合因素影响下的系统误码率和信道容量变化的数值结果和相关结论,与只考虑单个因素影响相比,综合后系统误码率至少增大了1倍,信道容量至少降低了30%。

- For the factors that influence V-BLAST system antenna array correlation and the circumstance under the action of various factors on the system performance, based on V-BLAST system model and the antenna correlation theory, we put forward the corresponding theoretical model and system performance analysis model which influencing the antenna correlation, and the multiple factors and comprehensive simulation is carried out for the array correlation and system bit error rate and channel capacity. The numerical results and relevant conclusions of the changes of system bit error rate and channel capacity are obtained, under the influence of single and comprehensive factors such as antenna spacing, beam arrival Angle, Angle expansion and coupling. In comparison of the influence by single factor, under comprehensive factors, the system bit error rate is doubled at least and the channel capacity is decreased by 30% at least.
