摘要
针对独立分量分析算法忽略噪声这一缺点,引入基于噪声模型的噪声独立分量分析,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算法进行仿真比较,结果表明本文引入的方法性能更优,稳健性更好,对实际信道的适应性更强.
In order to remove the bias, a noise ICA algorithm based the noise model is introduced and the multi-user detection method based this algorithm is deduced. The algorithms are simulated to compare the performance of the two kinds of multl-user detection methods which are based the normal ICA algorithm and the noise ICA algorithm. Simulation results indicate that noise ICA algorithm method has better performance.
