On MIMO for UTRA LTE

The long term evolution of UMTS (Universal Mobile Telecommunications System), UTRA LTE, is based on OFDM (orthogonal frequency division multiplexing) combined with MIMO (multiple-input multiple-output) techniques. In particular, the Alamouti and the V-BLAST (Vertical Bell Labs Layered Space Time) schemes are seen as interesting MIMO concepts. In this communication, the authors will compare these two MIMO schemes w.r.t. the achievable performance in the UTRA LTE downlink using up to two transmit and two receive antennas.
