ABSTRACT:
A method and system incorporating the use of interference cancellation during synchronized demodulation of a code division multiple access (CDMA) signal is described. A wireless communications receiver uses synchronized demodulation techniques to estimate the data contained in multiple orthogonal sub-channels of multiple CDMA signals. In response to these estimates an ideal waveform is constructed for each CDMA signal. These ideal waveforms are subtracted from the original signal received to form an interference-cancelled version of the original signal which is used when demodulating individual orthogonal sub-channels.
