Abstract:
1. A cellular communication system Multiple-In Multiple-Out (MIMO)transmitter, comprising: a plurality of antennas, wherein each antenna is associated with a subset of training sequences a first of the plurality of antennas being associated with a first of the subsets of training sequences and a second of the plurality of antennas being associated with a second of the subsets of training sequences and the subsets of training sequences are disjoint and form a set of training sequences associated with a cell of the MIMO transmitter; a training sequences selector for receiving an indication of a first antenna for transmission of a first message, for receiving an indication of a second antenna for transmission of a second message, for selecting a first training sequence for the first message, the training sequence being selected from the subset of training sequences associated with the first antenna, and for selecting a second training sequence for the second message, the second training sequence being selected from the second of the subsets of training sequences which is associated with the second antenna; a message generator for generating the first message, which includes the first training sequence so that the first message is identifiable as being associated with the first antenna; and for generating the second message, which includes the second training sequence so that the second message is identifiable as being associated with the second antenna; and a transceiver for transmitting the first message on the first antenna, and the second message on the second antenna.
