Abstract

A mobile station for use in a wireless network comprising a first base station that transmits user data streams in a forward channel using a multiple-input, multiple-output (MIMO) antenna system. The mobile station implements a virtual MIMO antenna system to receive MIMO data signals transmitted by the first base station. The mobile station comprises first and second transceivers. The first transceiver receives the MIMO data signals transmitted by the first base station and stores a first plurality of MIMO data signal samples in a memory. The second transceiver receives directly from a second mobile station a second plurality of MIMO data signal samples received by the second mobile station from the first base station. The second plurality of MIMO data signal samples are stored in memory. A MIMO algorithm generates from the first and second plurality of samples the user data streams transmitted by the base station.
