例句與用法
- 3 daugman j g . high confidence visual recognition of persons by atest of statistical independence
相對而言，高精度的配準操作可以提高整個識別系統(tǒng)的識別精度。 - The preprocessing obviously stands out the non - gaussianity of the individual components in the signals to satisfy the ica condition , i . e . statistical independence of sources
同時指出，對信號進行自相關(guān)預(yù)處理，可以突出信號的非高斯成分，較好地滿足獨立分量分析的前提條件，即源信號統(tǒng)計獨立。 - Based on ica post processing matched filter multi - user detection lets the output of traditional matched filter to initialize the ica iterations , not only the known spread information of interesting user is used to overcome the uncertainness of ica , but also the character of statistical independence is used . the simulation results show that it advances the ability of traditional detector when the signal - noise - ratio is large . keywords code division multiple access ; independent component analysis ; channel estimation ; matched filter ; blind multi - user detection
基于ica后處理的匹配濾波多用戶檢測是用傳統(tǒng)的檢測器的輸出來初始化ica的迭代，它不但充分利用多用戶信號的已知信息，克服了ica的不確定性問題，同時也充分利用了多用戶信號的統(tǒng)計獨立性，仿真實驗結(jié)果證明這種多用戶檢測算法在高信噪的情況下，誤碼性能改善隨著信噪比的提高不斷增加。
