Abstract :
Applies a multicarrier signalling technique to a direct sequence CDMA system. This type of signalling has the desirable properties of exhibiting a narrowband interference suppression effect, along with robustness to fading, without requiring the use of either an explicit RAKE structure or an interference suppression filter. The authors use bandlimited spreading waveforms to prevent self-interference, and evaluate the system performance over a frequency selective Rayleigh channel in the presence of partial band interference
