| Abstract: | Multi access interference (MAI) is the major factor degrading the CDMA system performance and capacity. According to the characteristics of MAI in CDMA systems, a multi user detector is designed by a new hard decision parallel decision algorithm for MAI cancellation. Analysis and simulation results show that this detector performs better and has larger capacity to restrain near far impact than the conventional ones, and hence has good potential for practical application. |
