Then, to reduce the complexity, we propose a two-step suboptimalalgorithm that separates subcarrier and power allocation.
随后为降低求解该优化问题的复杂度，提出两步次优算法，将问题分解为子载波分配和功率分配。

The fading factor restricts the length of the data which processed by the Kalman filter. And we use"one step"approximation algorithm to calculate the suboptimal fading factor.
引入的渐消因子限制了卡尔曼滤波中处理数据的长度，采用一步近似算法对次优渐消因子进行计算。

This technique is based on the suboptimal subspace blind minimum mean square error (MMSE) algorithm of multiuser detection.
