Abstract
This paper provides some analytical and experimental results in comparing the non-stationary tracking characteristics of LMS and RLS in multi-user detection. It is shown that under slow fading conditions, the LMS algorithm outperforms the RLS algorithm. In both cases, only the Doppler shift of the user of interest, but not that of the interference, affects the tracking performances
