Abstract :
Deeply analyses the signal characteristics of CDMA receiver on unideal power control instance, deduces the receiving signal model of multi-cell. Presents the asynchronous multi-user detection method based on FastICA, which is naturally near-far and multiple-access interference resistant. The simulation results show that: this method has less iterative time and small calculation quantity and good performance of multi-user detection, which is very suitable for asynchronous multi-user detection on unideal power control and enhance the capability of multi-user receiver.
