摘　　要：分析了基于IEEE802.16d标准的正交频分复用(Orthogonal Frequency Division Mul-tiplexing,OFDM)系统在SUI-3信道下的误码性能,并对发射端的帧结构以及组帧方式作了详细说明。通过实验仿真发现利用帧前导做信道估计得出的误码性能要优于没有信道估计的情况。The performance of bit error under SUI - 3 channel was analysed based on OFDM system according to IEEE802.16d standard, and the frame structure of transmitter and frame composed pat- tern were detailedly illustrated. Practising simulation indicates that the performance of bit error got from frame preamble used for channel estimation is better than from no channel estimation.
