LTE for UMTS - OFDMA and SC-FDMA Based Radio Access 关于随机接入很好的一本书籍是针对LTE系统的。(LTE for UMTS- OFDMA and SC-FDMA Based Radio Access on the random access good books for a LTE system.)

特别好用的图像分类算法！！！输入图像 输出分类结果(A particularly useful algorithm for image classification!!! Input image output classification results)

说明：  为了提高认知无线电中感知用户对授权用户(主用户) 的检测概率,提出一种新的基于循环 谱统计量的主用户信号检测算法. 该算法利用循环谱离散频域平滑方法,对信号的循环谱在循环频 率处建立合理的检测统计量,然后求解得到对应不同虚警概率的判决门限,以使感知用户能检测信 噪比更低的授权用户信号.(To increase the detection probability of sensing users for licenced users (primary signals) in the cognitive radio , it put s forward a new primary users signal method based on cyclic spect rum statis2 tics. By using discrete f requency smoothing of cyclic spect rum , this algorithm establishes the reason2 able detection statistics on the cyclic f requency of signal cyclic spect rum , then solves and obtains the decision threshold correspond to different false alarm probability , as a result , making the sensing users can detect licenced users signal under lower signal in noise ratio (SNR) .)

说明：  qpsk调制在awgn/rayleigh信道下的误码性能比较，以及信号的功率谱和星座图(QPSK modulation in awgn/Rayleigh Channel Performance Comparison of error, and the signal power spectrum and constellation)

说明：  《先进PID控制及matlab仿真》一书的源程序(&quot Advanced PID Control and matlab simulation&quot of the source book)

说明：  给予双层搜索的峰均功率比抑制技术仿真 循环是1000 (DLPS)

一个简单的动网格事例,该程序用MATLAB语言编写.(a simple moving mesh example, the procedures used MATLAB language.)

代码为QPSK半分析方法计算误码率，下载后直接运行就行了(code for QPSK semi-analytic method BER, downloaded directly running on the line)

说明：  内容：运用PM算法识别空间目标。程序中附有注释，可改变方向角，运算速度比music算法快，本人毕设程序，绝对可用。(Content: The use of PM space target recognition algorithm. Annotated program, you can change the direction of the angle calculation algorithm is faster than the music, I set up the program, absolutely free.)

文字分割 ，进行基本的文字分割，为后继的步骤做工作(Text segmentation, a basic text segmentation, to do work for the subsequent steps)
