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。

英文摘要：

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 de- coding. To reduce the network overhead, proper selection of APs for a better package delivery rate is abso- lutely. 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 perform- ance in MIMO network. Finally, the algorithm is implemented on USRP platform and the experiment results indicate the effectiveness of the proposed method.
