Interference suppression factor in DS-CDMA systems
Fumiyuki Adachi, D.K. Kim · Electronics Letters · 1999
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 onto 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.
