Abstract

"The work presented in this paper aims at evaluating the 2 Mbps data service (without channel coding) in the 1.28 Mcps TDD option for UMTS technology using the Transmit Adaptive Antennas (TxAA) algorithm. The 2Mbps service is used in indoor propagation environments for downlink (DL) transmissions, from the Base Station (BS) to the User Equipment (UE). There is only 1 receive antenna at the UE and 1, 2, 4 or 8 transmit antennas at the BS to perform either a classical transmission or the Transmit Adaptive Antennas algorithm as a closed loop transmit diversity scheme for dedicated channels. The Minimum Mean Square Error Block Linear Equaliser (MMSE-BLE) is used at the UE as Joint Detection (JD) solution for retrieving data."
