This paper describes configuration, analysis and characteristics of an M-ary CDMA using Interference Cancellation (IC) with the Walsh orthogonal code. The IC reduces interference signals of other Personal Stations (PSs), improves communication quality and increases system capacity in a cell. In this IC scheme, cancellation value is calculated from the correlation value, then the cancellation value correspond to the variation of fading. This results of the analysis represent that the limitation of the system capacity becomes equal to the spreading ratio when IC is used. A computer simulation shows that the simultaneously accessing users per cell are obtained up to 40 channels using 2⁶ Walsh codes as a spreading codes under Rayleigh fading conditions.
