  title = {Pilot Aided Channel Estimation for Short-Code DS-CDMA},
  address={Prague, Czech Republic},
  abstract={This paper investigates pilot based channel estimation techniques for short code DS-CDMA in a multipath environment. It will be shown that the conventional correlatibe estimation algorithm is biased and very sensitive to multi-user interference (MUI).    Therefore, we suggest two advanced estimation algorithms. The first one eliminates the inherent path cross talk and yields an unbiased estimate while still suffering from MUI. The second approach suppresses the influence of the MUI by incorporating a linear interference suppression into the channel estimation algorithm. It will be shown that significant performance improvements can be achieved with the proposed algorithms especially under extreme near-far conditions.},
