代码说明:

  主要用途是对抗多径衰落。由于多径衰落的存在,使得同一个帧由于路径不同,到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰,影响 性能。另外,由于有了循环前缀,使得IFFT FFT操作把原来的线性卷积变成循环卷积,大大简化了相应的信号处理复杂度(Graduate study do not to upload copyrighted controversial content and Trojan code and agent software to access foreign sites)

  • OFDM_lx
    很实用的一个OFDM仿真程序,OFDM采用BPSK、QPSK、16QAM、64QAM4种调制方式。按照星座图,将每个子信道上的数据,映射到星座图点的复数表示,转换为同相Ich和正交分量Qch。(A very practical OFDM simulation program, OFDM the BPSK, QPSK, 16 qam, 64 qam4 kind of modulation method. According to the constellation diagram, each will be the data on the channel, the plural of constellation is mapped to a point, said into in-phase Ich and quadrature Qch. )
