这个第四代移动通信中，OFDM－MIMO的例子，是vblast的仿真代码(The fourth-generation mobile communications, OFDM-MIMO example is VBLAST simulation code)

为实现通信的终极目标五个W：任何人（whoever）在任何时间（whenever）任何地点(wherever)与任何他人(whomever)进行任何类型(whatever)的信息交换，则至少通信网的最后一段必须是移动通信系统。由此可见移动通信在现在及未来通信中的重要地位。(communications to achieve the ultimate goal of 5 W : Any person (whoever) at any time (whenever) any location (wherever ) and any other person (whomever) for any type (whatever) the exchange of information, communications network at least the last paragraph must be mobile communication systems. So mobile communications in the current and future communications to the important position.)
