老外写的关于OFDM调制，发送，接受仿真的论文，并附有源程序，对做OFDM仿真的初学者朋友很有帮助(Written by a foreigner on the OFDM modulation, sent, received papers Simulation, along with source code for beginners to do OFDM simulation Friend helpful)

输入一个一维行向量，输出一个以此为首行元素的实对阵矩阵。如：输入a=[4 9 5 3 6],再输入A=symm(a)(Enter a one-dimensional row vector, generate a symmetry matrix )

The M-file generates modulated signals using BPSK, QPSK, 16QAM and 64QAM modulation.

The model used for creating the reference voltage is shown in Fig. 4. First, photovoltaic output current (Ipv) and output voltage (Vpv) are passed through a first order low pass filter with a magnitude of G = 1 and a time constant of T = 0.01 seconds in order to filter out the high frequency components or harmonics from these signals as shown in Fig. 5 and Fig. 6. The filtered current and voltage signals (Ipv_F and Vpv_F) are then fed into the MPPT control block that uses the Incremental Conductance Tracking Algorithm. An algorithm that is based on the fact the slope of the PV array power curve shown in Fig. 7 is zero at the Maximum Power Point (MPP), positive on the left of the MPP, and negative on the right. The MPP can thus be tracked by comparing the instantaneous conductance (I/V) to the incremental conductance (∆ I/∆ V) [11] as in (1):
