MIMO系统的传输环境是移动的多径衰落环境，因此接收端必须消除接收信号的符号间干扰利通道间干扰。

The transmitting environment of MIMO system is always a mobile and multi path environment, so the receiver must get rid of the inter symbol interference and the inter channel interference.

由于室内环境复杂，多径传播、随机噪声干扰等影响较大，因此室内定位系统的算法研究具有挑战性。

Because the indoor environment is very complex, and it's greatly influenced by multipath propagation and random noise, the research on the algorithms of indoor location system is of great challenge.
