摘要： 针对WiMAX物理层基带仿真模型未采用SUI信道的问题，在理想同步情况下，综合考虑影响系统性能的各种因素，包括SUI信道、循环前缀(CP)长度、RS+CC编码和信道估计，运用Simulink对其进行评估。仿真结果表明，采用自适应调制编码或改变CP长度能平衡BER和数据速率。

Abstract: The baseband simulation model of WiMAX PHY-Layer does not take SUI channel into consideration. Aiming at this problem and under the conditions of perfect synchronization, this paper considers the factors effects the system performance synthetically, including SUI channel, the length of Cyclic Prefix(CP), RS+CC encoding, channel estimation, and evaluates them based on Simulink. Simulation results show that by changing the length of CP and using Adaptive Modulation and Coding(AMC), the balance between BER and data rate can be kept.
