Blind Multiuser Equalization for Time-Varying Channels

  title={Blind Multiuser Equalization for Time-Varying Channels},
  author={Harold Art},
We propose t w o methods for deterministic blind equalization of linear time-varying (LTV) channels with multiple users. Our approach is based on an LTI multichannel representation of LTV channels. With the first method, the multiuser channel is equalized up to an instantaneous mixture that is subsequently resolved by means of a POCS (projections onto convex sets) algorithm. The second method performs the entire equalization (including resolution of the instantaneous mixture) by means of a POCS… CONTINUE READING
