OFDM
- OFDM系统的不同编码如BPSK,QPSK,mQAM等在瑞利信道或高斯信道中传播的特性曲线分析。-The different coding of OFDM system in Rayleigh channel, or Gaussian channel spread features such as BPSK, QPSK, mQAM curve analysis.
qpsk
- 要求对有3条固定路径的AWGN多径信道中的QPSK系统进行BER性能仿真,并与在理想的AWGN信道中同样系统的BER性能进行比较。熟悉瑞利平坦衰落、莱斯平坦衰落与频率选择性衰落的特点,比较这些衰落信道的误码率。-Required to have three fixed-path AWGN multipath channels of QPSK system BER performance simulation, and in an ideal AWGN channel with the same
