Abstract :
We derive a blind subspace-based receiver algorithm suitable for asynchronous wideband CDMA with periodic codes in dispersive multipath channels. The algorithm is roughly equivalent to a previously presented algorithm by Wang and Poor (see IEEE Tr. Comm., no.1, 1998), but is often computationally more efficient. The algorithm is readily extended to multicode and multirate systems
