Firstly, based on the function and business requirement of system's target user, the thesis designed and implemented two important systems of the simulation platform: the coding system and the helping system. 首先,文中根据系统目标用户的功能和业务需求,设计并实现了构成仿真平台的两大系统:编码系统和帮助支持系统。
In addition to the use of pre-defined target system, developers can construct a new object ( known as user objects) to expand the system of pre-defined target, the target will be a variety of organically combined to form the PowerBuilder application. 除了使用系统预先定义的对象外,开发人员可以自行构造新的对象(称作用户对象),扩展系统的预定义对象,将各种对象有机地组合起来就构成了PowerBuilder应用程序。
If the total transmit power is fixed, then the optimization target is to maximize the number of user the system can support. 如果系统总的发送功率固定,那么优化目标是使系统支持的用户数最大化。
