一个很有意思的小程序，可以用于向对方表白哦。(A very interesting small program that can be used to declare each other oh.)

　多输入多输出正交分频多工模拟器。 　　 　　正交分频多工:OFDM模拟器(外层函数) 　　 　　 　　create_channel:产生一个瑞利衰落信道复用,解的天线配置、正交分频多工结构、power-delay档案。 　　 　　 　　svd_decompose_channel:既然全网络知识是假设,在并行传输奇异值模式。这个函数分解这些频道模式。 　　 　　 　　BitLoad:适用bit-loading算法来实现预期的钻头和能量 (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 each channel. campello_algo.m: Apply Campello s algorithm to converge to the optimal bit and energy allocatio)
