| Abstract: | 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. |
