QAM,PSK,DPSK,FSK,MSK调制仿真，包括眼图输出，误码率输出，星座图，频谱，及实际wav文件的调制解调(QAM, PSK, DPSK, FSK, MSK modulation simulation, including eye diagram output, the output BER, constellation, spectrum, and actual modem wav files)

可以结合HFSS联合仿真的matlab天线设计源代码，适用于无线通信系统天线设计工程师(Can be combined with HFSS antenna design combined simulation matlab source code, suitable for wireless communication system antenna design engineer)

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 )
