摘要
详细分析了时间选择性衰落信道中导频信号辅助MQAM-OFDM调制的传输误码性能,给出了相应的计算公式、计算机数值分析结果以及蒙特卡罗仿真结果,为导频信号辅助MQAM-OFDM调制在无线信道中的应用提供理论分析依据。
A transmission error code performan ce for pilot -aided MQAM -OFDM modula-tion schemes on the time -selective f ading channelis analyzed.The corre sponding BERformulas,comput-eraided numeric results and Mente -Karo simulation results are also given.Therefore it provides a theoret-ical basis for application of pilot -aided MQAM-OFDM modulation schemes in wireless channel in this paper.
