cdma channel meaning in English
码分多址信道
Examples
- Bling space - time multiuser detector in multipath cdma channels
的时域信道估计和多用户检测 - Blind space - time multiuser detection in multipath cdma channels
多径条件下的最优空时多用户检测 - With the increase of active user numbers in cdma channels , single user detector cannot effectively suppress mai
数学分析和仿真结果表明：该检测器具有实现复杂度低、跟踪速度快和健壮性强的优点。 - A multiuser detection method based on adaptive wavelet network is proposed . this method can effectively eliminate mai and white noise . a novel space - time matched filter combined with adaptive wavelet network in asynchronous multipath cdma channels is proposed
提出了基于自适应子波网络与空时匹配滤波方法，这种方法使用子波网络对阵列天线波束形成之后的输出进行后续处理，是一种单用户的检测方法。 - 3 a novel recursive least - square ( rls ) blind space - time receiver algorithm based on the constrained condition , which can completely avoid the matrix inversion introduced into by constraints ( comparing with the normal rls ) , is proposed for multi - path slow fading cdma channels . the computational complexity of this method is not only lower than that of the normal rls , but also lower than that of both lms and ls blind space - time receiver methods that are realized based on the rosen ' s gradient projection . and the speed of convergence of the presented rls blind space - time receiver algorithm is better than that of both lms and ls blind space - time receiver methods
3 、针对多径慢衰落信道下ds - cdma盲空时接收机中线性约束二次规划问题提出一种新的递归最小二乘算法，该算法完全避免因约束而引进的矩阵求逆运算(相对于常规的递归最小二乘算法) ，不但运算量比常规的要低，而且比基于rosen梯度投影实现的最小均方( lms )与最小二乘盲空时接收机算法还低，且收敛速度比基于rosen梯度投影实现的最小均方( lms )与最小二乘盲空时多用户检测都好，将提出的新的递归最小二乘算法与提出的数据选择方案结合起来可以进一步降低其运算量，具有很大的实用价值，最后通过仿真实验进一步分析了其性能。
