Abstract :
In a wireless DS-CDMA system, the interference power is suppressed by a factor greater than the spreading factor of the spreading code. An investigation into the interference suppression factor is presented and its simple frequency domain expressions for other-user interference from the same system and other systems are derived. Some numerical results are presented for two spectrally overlapped systems with different raised cosine Nyquist filters
