摘要
简要介绍了IEEE802.16a协议,并以802.16a协议中的三种物理层实现方式之一——WirelessMAN OFDM PHY为例,对其选用的前向纠错码(FEC)RS-CC进行了详细的阐述,同时对其不同种情况下的BER(误比特率)性能作了仿真,并对结果进行了分析。
This paper gives a brief outline of IEEE802.16a protocol. Take the WirelessMAN OFDM PHY which is one of the three implementation techniques of the physical layer as an example, we expatiate on the FEC method that it uses-RS-CC. Then the BER performances of it under different circumstances are simulated and some analysis of the results is given.
