    说明:  这是盲信号的代码 都已经通过编译了 做这方面的同仁可以参考一下 我觉得蛮惯用的(This is the Blind have passed code compiled into this area of reference for my colleagues I think it is pretty usual)

    仿真实现了谱相关系数和谱相关函数,谱相关函数使用了频域计算法。谱相关函数做的比较好,但谱相关系数的计算个人感觉仍需后来者继续改进(Simulation spectral correlation coefficient and spectral correlation function, the calculation of the frequency domain using the spectral correlation function. Spectral correlation function do better, but the spectral correlation coefficient calculated personal feeling is still a latecomer to continue to improve)

    正交频分复用是一种多载波宽带数字调制技术。相比一般的数字通信系统, 它具有频带利用率高和抗多径干扰能力强等优点,因而适合于高速率的无线通信系统。( OFDM Simulator -------------------------------------------------------------------------------- MIMO OFDM Simulator: OFDM.m: OFDM Simulator (outer function) create_channel.m: Generates a Rayleigh fading frequency-selective channel, parametrized by the antenna configuration, the OFDM configuration, and the power-delay profile. svd_decompose_channel.m: Since full channel knowledge is assumed, transmission is across parallel singular value modes. This function decomposes the channel into these modes. BitLoad.m: Apply the bit-loading algorithm to achieve the desired bit and energy allocation for the current channel instance. ComputeSNR.m: Given the subcarrier gains, this simple function generates the SNR values of each channel (each singular value on each tone is a separate channel). chow_algo.m: Apply Chow s algorithm to generate a particular bit and energy allocation. EnergyTableInit.m: Given the SNR values, form a table of energy increments for )
