记录我的一些收藏夹里的东东，很不错的，大家看看吧-record some of my favorites in the Eastern Lane, a very good, we look at it

正交空时块编码和进一步探索这最后一节中说明了，我们目前某些性能的正交空时块编码使用四个结果传输天线 （4 x 1 系统） 使用半速率编码，G4。我们期望的系统提供的 4 和 w 的多样性顺序。

xul调用c++xpcom例子,这几天在研究Xul ,调试通过了一个Xul做界面，通过js调用c++开发的xpcom的例子。感觉步骤比较繁杂，配置环境也颇费了点时间，所以就把整个开发过程作了一个记录-xul call c++ xpcom example, these days in the study Xul, debug interface, the adoption of a Xul do, through the js call c++ development xpcom example. Sense steps to more complicated, and configure the environment has also gone through quite some time, so put the entire development process was a record of

m序列的生成，包括在有限域GF(p)中的基于不同p取值，不同级数条件下的本原多项式多种选择条件下的m序列生成。-m sequence generation, including in GF (p), the p value based on different, different levels under the conditions of primitive polynomial number of options under the conditions of m-sequences generated.

一个序列调制的BPSK和LDPC码具有R = 5 / 15是从信道传输速率编码的符号。LDPC码的奇偶校验矩阵是经济合作发展组织在h.dat。信道是AWGN一零均值和方差N0 / 2。对数的消息传递算法应用在接收机。本代码给出了Pb–Eb/N0曲线迭代次数1，10和100。

1)生成2KHz和8KHz的混合信号，使该信号通过上述滤波器，观察滤波前后的波形变化和频谱分布情况。 2) 在改信号中加入高斯白噪声，观察滤波前后的波形变化和频谱分布情况3) 将上述滤波器改为中心频率为100KHz的带通滤波器，信号源为带外的90KHz和带内的100KHz的混合正弦信号，。 4) 用M文件实现上述低通滤波器。 -1) 2KHz and 8KHz to generate the mixed-signal, so that the signal through the above-mentioned filter, filter before and after observation of the waveform and spectrum distribution of the changes. 2) add to the signal in white Gaussian noise was observed before and after filtering and spectral waveform changes in the distribution of 3) will be replaced by the above-mentioned filter center frequency of 100KHz band pass filter, the signal source for the band and the band of 90KHz 100KHz Sine of the mixed signals. 4) achieve the above-mentioned documents with M low-pass filter.
