Examples
- 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。 - Traditional multiuser detector make good use of all signals which resuilt in multiple access interference so that it provides optimum mai resistance . ( 1 ) nevertheless , it assumes that the receiver can acquire the signature waveform and timing of desired user and the interfering users ; ( 2 ) it has no ability to suppress intercell multiple access interference ; ( 3 ) it cannot be applied in downlink channels . adaptive multiuser detector eliminates the need to know the signature waveforms and the timing of the interferes and has to need training data sequences for every active user
传统多用户检测在单用户检测技术基础上，充分利用造成多址干扰的所有用户的信息进行联合检测，从而具有良好的抗多址干扰能力，但存在一些缺陷： ( 1 )不仅要求知道期望用户的地址pn码及其定时信息，还要求其他干扰用户的地址pn码及其定时信息； ( 2 )不能消除其他相邻小区的多址干扰对本小区的影响； ( 3 )不能直接应用在cdma移动通信系统中的下行链路。
