摘要
针对独立分量分析算法忽略噪声这一缺点,将基于噪声模型的噪声独立分量分析引入,并进行分析,得到基于噪声独立分量分析的多用户检测方法。并与基于无噪模型的独立分量分析算法的多用户检测性能进行仿真比较,结果表明本文引入的方法检测性能更优。
In order to remove the bias,we introduce a noise ICA algorithm based on the noise model and deduce the multi-user detection method based on this algorithm.To compare the performance of the two kinds of multi-user detection methods which are based on the normal ICA algorithm and the noise ICA algorithm,we simulate the two methods.Simulation results indicate that noise ICA algorithm method has better performance.
