该项目用于降低 PAPR ofdm 系统中，通过使用不同的技术。OFDM 峰均功率比的主要缺点是降低系统性能，因为它在 ofdm 到平均功率高的高峰。并且在这里我们使用非线性压扩变换来减少此峰均比。

In this simulink model , BPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.-In this simulink model , BPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.

ROC curves illustrate performance on a binary classification problem where classification is based on simply thresholding a set of scores at varying levels. Lenient thresholds give high sensitivity but low specificity, strict thresholds give high specificity but low sensitivity the ROC curve plots this trade-off over a range of thresholds (usually with sens vs 1-spec, but I prefer sens vs spec this code gives you the option). It is theoretically possible to operate anywhere on the convex hull of an ROC curve, so this is plotted too. The area under the curve (AUC) for a ROC plot is a measure of overall accuracy, and the area under the ROCCH is a kind of upper bound on what might be achievable with a weighted combination of differently thresholded results from the given classifier -ROC curves illustrate performance on a binary classification problem where classification is based on simply thresholding a set of scores at varying levels.

摘要 在一个移动 ad hoc 网络中移动节点的移动性和资源约束可能会导致网络分区或性能退化。提出了几种数据复制技术，尽量减少性能退化。其中大多数假设所有移动节点进行充分协作共同分担他们的内存空间。在现实中，但是，一些节点可能会自私地决定只有部分，或根本不与其他节点进行合作。这些自私的节点就可以减少总体网络中的数据可访问性。在此文件中，我们检查自私的副本分配视角移动 ad hoc 网络中节点的影响。我们长期在这种自私的副本分配。尤其是，我们开发一种自私的节点检测算法，认为部分自私和新颖副本分配技术来适当应付自私副本分配。进行的模拟演示拟议的办法在性能上优于传统合作副本分配技术在数据可访问性、 沟通成本和平均查询延迟。
