sample correlation matrix造句

• Sample correlation matrix
  样本相关矩阵
• It is especially attractive for the downlinks and suppressing intercell mai . when multiuser detector is adapted in blind mode , it usually adopts eignvalue decomposition or singularvalue decomposition of received sample correlation matrix and tracking alrithgms , which result in high computational complexity . at the same time , approximation computation in tracking alrithgms also result in slow convergence
  为实现盲自适应检测，通常采用对接收信号样本矩阵进行特征值分解( evd )或奇异值分解( svd )后进行跟踪，由此带来的子空间秩跟踪使得实现复杂度很高；另一方面，在跟踪算法中考虑一些实际情况而作出近似处理，从而引起误差积累和正交性误差，导致每次跟踪开始阶段跟踪速度变慢。
