<p>PURPOSE: To provide a multi-user interference eliminating device, that can adaptively update an antenna weight, even at 2nd and subsequent stages and generate the antenna weight with high accuracy by using a received signal whose interference is eliminated. CONSTITUTION: A multiplier 29 multiplies a coefficient £1-(1-α)¬m-1| by a symbol replica received from a preceding stage to correct a gain, and an antenna signal recovery section 30 converts the symbol replica, subjected to gain correction, into an antenna signal. Adders 31-1 to 31-N add the antenna signal converted by the antenna signal recovery section 30 to outputs of inverse spread means 11-1 to 11-N and provides an output of the sum to an antenna weight adaptive update section 17. The antenna weight adaptive update section 17 uses the output signal, to adaptively update the antenna weight.</p> |
