BER
这是一个matlab和optisystem联合调试用的误码率计算程序，里面的文件报过一个可以用optisystem7和optisystem13可以打开的OSD仿真图，还有一个MATLAB计算BER的程序。给出了如何设置系统的大纲。从OptiSystem的电信号输入到Matlab组件。当OptiSystem运行时，它将调用Matlab组件中的M文件，处理数据，然后将所得的电信号导出回OptiSystem。然后将输出信号连接到BER分析仪。经过我调试，文件齐全，放心下载(The attached image gives an outline of how the system should be setup. You should start with inputting the electrical signal from OptiSystem into a Matlab component. When OptiSystem runs, it will call the M-file in the Matlab component, process the data, and then export the resulting electrical signal back into OptiSystem.The output signal is then connected to the BER Analyzer.)

Overcoming_IP_Address_Issues_with_GPRS_Remote_Mon
GPRS is a communication technology that allows data
acquisition systems to overcome the difficulty of cabling for
wide area remote sites. GPRS applications are becoming more
and more prevalent due to the ease with which they can be
implemented, but the dynamic IP address issues associated
with GPRS networking continue to frustrate system
integrators.

OFDM信号频谱感10
说明： 前已提出的频谱感知方法主要包括匹配滤波器检测、 能量检测、 循环平稳特征检测以及多分辨率频谱感知. 这些方法均为单节点感知方法.然而，在阴影和深度衰落情况下， 单个节点的感知结果并不可靠， 因此， 需要对多个节点的感知结果进行融合，以提高检测可靠性， 即协作感知技术. 文献采用“或” 准则对各个 CR 感知结果进行融合. 文献则提出了基于 D-S 证据理论的协作频谱感知算法，虽然该算法的性能比“或” 准则或“与”准则要好， 但需要存储大量历史信息， 算法的计算复杂度也很高. 文献中分析了采用似然比检测(likelihood ratio test， LRT) 的软判决与采用“与” 准则的硬判决的性能， 结果表明采用软判决的协作感知性能更优(Previously proposed spectrum sensing methods mainly include matched filter detection, energy detection, cyclostationary feature detection and multi-resolution spectrum sensing. These methods are all single node sensing methods. However, in the case of shadow and deep fading, the sensing results of single node are not reliable, so, It is necessary to fuse the sensing results of multiple nodes to improve the detection reliability, i.e. cooperative sensing technology. In the literature, "or" criterion is used to fuse the CR sensing results. In the literature, a cooperative spectrum sensing algorithm based on D-S evidence theory is proposed. Although the performance of the algorithm is better than "or" criterion or "and" criterion, a large amount of historical information needs to be stored, The computational complexity of the algorithm is also very high. In the literature, the performance of the soft decision based on the likelihood ratio test)
