Multistage Interference Cancellation with Decision Directed Channel Estimation in Multirate DS/CDMA on a Mobile Radio Channel
نویسندگان
چکیده
A combination of a hybrid interference cancellation (IC) scheme and decision directed channel estimation is proposed for the uplink of multirate direct-sequence code division multiple access (DS/CDMA) systems communicating over mobile radio channels. The hybrid IC scheme includes both non-decision directed and decision directed IC, joined together with a modified RAKE combiner for utilization of the diversity. The channel estimator is a decision directed minimum mean square error estimator that utilizes the fading correlation. The performance is evaluated via computer simulations for a multiple data rate scheme, parallel channels, in a multipath environment.

متن کاملInterference Cancellation for Multirate Multiuser Systems
Multistage successive interference cancellation (SIC) and multistage parallel interference cancellation (PIC) are compared under two different realistic dual rate asynchronous DS-CDMA schemes. The effect of power control and imperfect channel side information are also considered. Multistage SIC outperforms singleor multi-stage PIC for any conditions considered.

We propose an adaptive two-stage receiver for a scrambled multirate DS-CDMA downlink. The first stage consists of adaptive FIR equalization generating tentative hard decisions, while the second stage involves adaptive inter-chip interference (ICI) cancellation. Here we detail the adaptive ICI stage, which is based on a lowcomplexity decision-directed LMS channel identification algorithm; the fi...
