用systerm generation完成BPSK的调制解调过程，这里原理简单易懂，程序来自一本日本书。(Systerm generation with the completion of the BPSK modulation and demodulation process, here the principle of easy-to-read, the program comes from a Japanese book.)

MIMO_OFDM的信道估计，方法较多，性能很好，十分完整而强大的程序(MIMO_OFDM channel estimation methods are more good performance, very complete and powerful program)

选择两个函数做卷积运算，本实验里可供选择的函数有矩形窗函数，锯齿波函数和sinc函数，观察选取函数的波形(Select convolution of two functions to do this experiment choice of function has rectangular window function, sawtooth wave function and the sinc function, observe the waveform selection function)

The receiver performance is quantified by depicting the receiver operating char- acteristics (ROC) curves. This curves serve as a tool to and study the performance of a sensing scheme. ROC graphs are employed to show trade-of vs between detection probability and false alarm rates, (i.e. PD versus PFA), thus allowing the determination of an optimal threshold. To illustrate the performance of energy detectors, we generate complementary ROC curves (the average probability of miss detection $ P_{md} 1 - P_d$ versus the false alarm probability $P_f$ for different receiver structures and in different fading environments.Fig. 1 illustrates the complementary ROC curves for a single channel reception (no diversity) over AWGN channels. This figure depicts the complementary ROC curves for energy detectors.
