Communication system simulation can be classified into two categories,one is the link level simulation and another is system level simulation.
通信系统的仿真一般可以被分为两种:链路级仿真和系统级仿真。

本文中,我们参照LTE的技术规范以及3GPP RAN4工作组的提案搭建了一个链路级仿真器,然后以此作为仿真平台来验证所提出的算法。
We refer to LTE's specifications and proposals of 3GPP RAN4 WG to construct a link level simulator. And then use it as the platform to validate the proposed algorithms.
在之前的文献中,链路级和系统级仿真器之间一般使用平均值和真实值接口的方法,但是由于这两种方法的不精确性和复杂性。
Previously, Average Value Interface and Actual Value Interface have usually been used. Due to both inaccuracy and complexity, probably they are not effective in OFDM/multi-carrier network evaluation.
