The cross correlation of pixels between two frames regarding background interframe continuity and foreground discontinuity is also computed. 同時(shí)，基于背景的幀間連續性和前景的不連續性，計算像素幀間的互相關(guān)系數。
However, different relative delay between users results in distinct partial correlation coefficients thus bringing about distinct performance of multiuser detectors. 然而，異步用戶(hù)間不同的相對時(shí)延將引起不等的部分互相關(guān)系數，從而也導致不一樣的多用戶(hù)檢測性能。
