摘要

对于无线MIMO系统,协作式的网络设计十分重要,而协作式的网络设计中如何选择合适的无线接入点(Access Point,AP)进行联合解包是一个重要问题。减少网络开销的同时,选择合适的AP进行解包,得到较好的解包率。在设计系统的过程中,对协作式MIMO系统的码元解码性能进行了全面的评估,并且探索了对于不同的AP选择方式与系统解码性能之间的关系。然后提出了简单有效的AP选择算法,该方法在MIMO网络中有着近似最优的性能表现。最后在USRP实验平台上对该算法进行了实现并验证了算法的效果。
        For wireless MIMO system,the design of collaborative network is very important. Meanwhile,a critical issue for this design is how to choose appropriate wireless access points( AP) for collaborative decoding. To reduce the network overhead,proper selection of APs for a better package delivery rate is absolutely. In the process of system design,the symbol-decoding performance of collaborative MIMO system is comprehensively evaluated,and the differences of between the AP selection methods also explored. Then a simple and effective AP selection algorithm is proposed,and this algorithm has a nearly-optimal performance in MIMO network. Finally,the algorithm is implemented on USRP platform and the experiment results indicate the effectiveness of the proposed method.
