Jin-Il Kim, Suk-Hyon Yoon, Sung-Jin Kang, Changeon Kang · Electronics Letters · 1998
A channel estimation technique in the uplink of a noncoherent DS/CDMA system with M-ary orthogonal signalling over multipath fading channels is considered. This method is used for the multiuser interference cancellation with coherent detection. The performance of the proposed multiuser detector is compared with that of a conventional detector and a significant improvement of performance is shown.
