8338 数值分析结果表明,功率比在一定范围内时,与正交多址接入的协作中继方案相比,该方案的传输速率提高了13.7%左右; Numerical analysis results show that the power ratio within a certain range, compared with the collaboration of the orthogonal multiple access relay scheme, the scheme of transmission rate increased by about 13.7%;
8339 当两种方案传输速率相同时,该方案的功率节约30%左右。 When two kinds of solution phase transmission rate at the same time, the scheme of power saving is about 30%.
8340 高分辨海杂波可以采用复合高斯模型进行建模,纹理分量决定了杂波的非高斯特性以及后续的检测算法。 High-resolution sea clutter compound gaussian model may be used for modeling, texture component determines the non-gaussian characteristics of clutter and subsequent detection algorithm.
8341 传统自适应检测算法假设纹理在距离维独立同分布(independent and identically distributed,IID),忽略了实测海杂波纹理相关性。 Traditional adaptive detection algorithm assumes that the texture in the distance d independent identically distributed (independent and identically distributed, IID), ignores the observed sea clutter ripple bedding correlation.
