Linear MMSE receiver using hidden training sequence in multipath channel for the W-CDMA system

A linear MMSE receiver using a hidden training sequence was proposed for the DS/CDMA system (S.Y. Jung and D.J. Park, 2003). The hidden training sequence, which uses a fraction of the informative sequence's transmitting power as a training sequence, was utilized for receiver design. In this paper, the proposed scheme is extended to the multipath channel case for the W-CDMA system. The performance of the proposed scheme is analyzed and confirmed through computer simulations.
