BEAMFORMING

摘要

The embodiments herein relate to a method in a transmitter for transmitting a data burst to a receiver in a system supporting GSM and/or EGPRS. The transmitter is arranged to make its transmissions with or without beamforming. The transmitter comprises at least two Tx antennas. When the data burst is beamformed, the transmitter transmits the data burst to the receiver through at least one of the at least two Tx antennas. The data burst comprises a common training sequence. When the data burst is non-beamformed, the transmitter transmits the data burst to the receiver through each of the at least two Tx antennas. The data burst comprises a respective antenna specific training sequence.
